The Dam Busters (film)

In early 1942, aeronautical engineer Barnes Wallis is struggling to develop a means of attacking Germany's dams in the hope of crippling German heavy industry. Working for the Ministry of Aircraft Production, as well as his own job at Vickers, he works feverishly to make practical his theory of a bouncing bomb which would skip over the water to avoid protective torpedo nets. When it hit the dam, backspin would make it sink whilst retaining contact with the wall, making the explosion far more destructive. Wallis calculates that the aircraft will have to fly extremely low (150 feet (46 m)) to enable the bombs to skip over the water correctly, but when he takes his conclusions to the Ministry, he is told that lack of production capacity means they cannot go ahead with his proposals.

Angry and frustrated, Wallis secures an interview with Sir Arthur "Bomber" Harris (played by Basil Sydney), the head of RAF Bomber Command, who at first is reluctant to take the idea seriously. Eventually, however, he is convinced and takes the idea to the Prime Minister, who authorises the project.

Bomber Command forms a special squadron of Lancaster bombers, 617 Squadron, to be commanded by Wing Commander Guy Gibson, and tasked to fly the mission. He recruits experienced crews, especially those with low-altitude flight experience. While they train for the mission, Wallis continues his development of the bomb but has problems, such as the bomb breaking apart upon hitting the water. This requires the drop altitude to be reduced to 60 feet (18 m). With only a few weeks to go, he succeeds in fixing the problems and the mission can go ahead.

The bombers attack the dams. Eight Lancasters and their crews are lost, but two dams are breached and the overall mission succeeds. Wallis later encounters Gibson, clearly affected by the loss of the crewmen, but Gibson stresses the squadron knew what they were facing but they went in regardless of the odds. Before they part Wallis asks if Gibson will finally get some sleep. Gibson says he cannot; he has to write letters to the dead airmen's next of kin.

In credits order.

Following the success of the book The Dam Busters (a RAF-approved history of 617 Squadron), Robert Clark the head of production at Associated British Picture Corporation (ABPC) approached its author Paul Brickhill about acquiring the film rights as a vehicle for Richard Todd. The company's production manager was, however, of the opinion that, due to its numerous personnel and raids, it would not be able to film the book in its entirety. As a result, Clark requested that Brickhill provide a film treatment which described his vision for the film. Brickhill agreed to do it without payment in the hope of selling the film rights. To assist him, Clark teamed him up with Walter Mycroft who was the company's director of production.[5] Brickhill decided to concentrate the film treatment on Operation Chastise and ignore the later raids.

After the Air Ministry agreed to make available four Lancaster bombers at a cheap price which helped make the production viable, Associated British decided to proceed with the film and agreed with Brickhill on the film rights in December 1952 for what is believed to have been £5,000.[6] After considering C.S. Forester, Terence Rattigan, as well as Emlyn Williams and Leslie Arliss, R. C. Sherriff was selected as the screenwriter with planned August delivery of the screenplay.[7] Sherriff agreed with Brickhill's opinion that the film needed to concentrate on Operation Chastise and exclude the later operations covered in the book.

In preparation for writing the script, Sherriff met with Barnes Wallis at his home, later returning accompanied by Brickhill, Walter Mycroft and production supervisor W.A. "Bill" Whittaker on 22 March 1952 to witness Wallis demonstrating his original home experiment. To Wallis's embarrassment he couldn't get it to work, no matter how many times he tried.[8]

Just prior to the film's scheduled release, Guy Gibson's widow Eve took legal action to prevent it, and Brickhill and Clark were mired in months of wrangling with her until references to her husband's book Enemy Coast Ahead were included.

The flight sequences of the film were shot using real Avro Lancaster bombers supplied by the RAF. The aircraft, four of the final production B.VIIs, had to be taken out of storage and specially modified by removing the mid-upper gun turrets to mimic 617 Squadron's special aircraft, and cost £130 per hour to run, which amounted to a tenth of the film's costs. A number of Avro Lincoln bombers were also used as "set dressing".[9] (An American cut was made more dramatic by depicting an aircraft flying into a hill and exploding. This version used stock footage from Warner Brothers of a Boeing B-17 Flying Fortress, not a Lancaster.)

The Upper Derwent Valley in Derbyshire (the test area for the real raids) doubled as the Ruhr valley for the film.[10] The scene where the Dutch coast is crossed was filmed between Boston, Lincolnshire, and King's Lynn, Norfolk, and other coastal scenes near Skegness. Additional aerial footage was shot above Windermere, in the Lake District.

While RAF Scampton, where the real raid launched, was used for some scenes, the principal airfield used for ground location shooting was RAF Hemswell, a few miles north and still an operational RAF station at the time of filming. Guy Gibson had been based at Hemswell in his final posting and the airfield had been an operational Avro Lancaster base during the war. At the time filming took place it was then home to No. 109 Squadron and No. 139 Squadron RAF, which were both operating English Electric Canberras on electronic countermeasures and nuclear air sampling missions over hydrogen bomb test sites in the Pacific and Australia. However, part of the RAF's fleet of ageing Avro Lincolns had been mothballed at Hemswell prior to being broken up and several of these static aircraft appeared in background shots during filming, doubling for additional No 617 Squadron Lancasters. The station headquarters building still stands on what is now an industrial estate and is named Gibson House. The four wartime hangars also still stand, little changed in external appearance since the war.[11]

Serving RAF pilots from both squadrons based at Hemswell took turns flying the Lancasters during filming and found the close formation and low level flying around Derwentwater and Windermere exhilarating and a welcome change from their normal high level solo Canberra sorties.

Three of the four Lancaster bombers used in the film had also appeared in the Dirk Bogarde film Appointment in London two years earlier.[12]

The theatre scene showing the spotlights was filmed at the Lyric Theatre Hammersmith. The dance troupe was The Television Toppers, on loan for one day filming, under contract from the BBC. The singer was June Powell,[13] she sings the 1942 song "Sing Everybody Sing" by John P Long.[14]

The film featured several actors who would go on to be stars of cinema and TV. Robert Shaw was featured as Gibson's engineer Flt Sgt Pulford[15] while George Baker played Flt Lt Maltby.[16] Patrick McGoohan had a bit part as a security guard,[17] standing guard outside the briefing room. He delivered the line—"Sorry, old boy, it's secret—you can't go in. Now, c'mon, hop it!", which was cut from some prints of the film. Richard Thorp played Sqn Ldr Maudslay. [18]

The film is largely historically accurate, with only a small number of changes made for reasons of dramatic licence. Some errors derive from Paul Brickhill's book, which was written when much detail about the raid was not yet in the public domain.

• Barnes Wallis said that he never encountered any opposition from bureaucracy. In the film, when a reluctant official asks what he can possibly say to the RAF to persuade them to lend a Vickers Wellington bomber for flight testing the bomb, Wallis suggests: "Well, if you told them that I designed it, do you think that might help?" Barnes Wallis was heavily involved with the design of the Wellington, as it used his geodesic construction method, though he was not actually its chief designer.
• Instead of all of Gibson's tour-expired crew at 106 Squadron volunteering to follow him to his new command, only his wireless operator, Hutchinson, went with him to 617 Squadron.
• Rather than the purpose as well as the method of the raid being Wallis's sole idea, the dams had already been identified as an important target by the Air Ministry before the war.
• Gibson did not devise the spotlights altimeter after visiting a theatre; it was suggested by Benjamin Lockspeiser of the Ministry of Aircraft Production after Gibson requested they solve the problem. It was a proven method used by RAF Coastal Command aircraft for some time.[26]
• The wooden "coat hanger" bomb sight intended to enable crews to release the weapon at the right distance from the target was not wholly successful; some crews used it, but others came up with their own solutions, such as pieces of string in the bomb-aimer's position and/or markings on the blister.
• No bomber flew into a hillside near a target on the actual raid. This scene, which is not in the original version, was included in the copy released on the North American market (see above). Three bombers are brought down by enemy fire and two crashed due to hitting power lines in the valleys.[27]
• Some of the sequences showing the testing of Upkeep—the code name for the weapon—in the film are of Mosquito fighter-bombers dropping the naval version of the bouncing bomb, code-named Highball, intended to be used against ships. This version of the weapon was never used operationally.
• At the time the film was made, certain aspects of Upkeep were still held classified, so the actual test footage was censored to hide any details of the test bombs (a black dot was superimposed over the bomb on each frame), and the dummy bombs carried by the Lancasters were almost spherical but with flat sides rather than the true cylindrical shape.
• The dummy bomb did not show the mechanism which created the back spin.
• Ammunition shown being loaded into a Lancaster is .50 calibre for M2 Browning heavy machine guns, not that for the .303 calibre machine guns found on the Lancaster in 1943.
• The scenes of the attack on the Eder Dam show a castle resembling Schloss Waldeck on the wrong side of the lake and dam. The position and angle of the lake in relation to the castle suggest that in reality the bombing-run would have needed a downhill approach to the west of the castle.
• Wallis states that his idea came from Nelson's bouncing cannonballs into the sides of enemy ships. (He also states that Nelson sank one ship during the Battle of the Nile with a yorker, a cricket term for a ball that bounces under the bat, making it difficult to play.) There is no evidence for this claim. In a 1942 paper, Wallis mentioned the bouncing of cannonballs in the 16th and 17th centuries, but Nelson was not mentioned.[28]
• In the film Wallis (Redgrave) tells Gibson and Young that a mechanical problem with the release gear has been solved as the engineers had the correct oil in store. This is false; there was a technical problem which was solved by Sgt Charles Sackville-Bryant, who was awarded the BEM for this.

The Dambusters received a Royal world premiere at the Odeon Leicester Square on 16 May 1955, the twelfth anniversary of the raid. Princess Margaret attended along with Eve Gibson, Guy Gibson's widow and his father. Richard Todd, Barnes Wallis and the surviving members of 617 Squadron who had taken part in the mission were all guests of honour.[29] The premiere helped to raise money and awareness for various RAF charities.

On 16 May 2008, a commemoration of the 65th anniversary was held at Derwent Reservoir, including a flypast by a Lancaster, Spitfire, and Hurricane. The event was attended by actor Richard Todd, representing the film crew and Les Munro, the last surviving pilot from the original raid, as well as Mary Stopes-Roe, the elder daughter of Sir Barnes Wallis.

On 17 May 2018, a commemoration of the 75th anniversary was held, in which a restored version of the film was broadcast live from the Royal Albert Hall, and hosted by Dan Snow. The film was simulcast into over 300 cinemas nationwide.[40]

Work on a remake of The Dam Busters, produced by Peter Jackson and directed by Christian Rivers, began in 2008. Jackson said in the mid-1990s that he became interested in remaking the 1955 film, but found that the rights had been bought by Mel Gibson. In 2004, Jackson was contacted by his agent, who said Gibson had dropped the rights. In December 2005, the rights were purchased by Sir David Frost, from the Brickhill family.[41] Stephen Fry wrote the script.[42]

In March 2007, it was announced it would be distributed by Universal Pictures, and StudioCanal.[43] Filming was planned to commence in early 2009, on a budget of US$40 million,[44] although no project-specific filming had begun by May 2009.[45] The project was delayed because Jackson decided to make The Hobbit.

Weta Workshop was making the models and special effects for the film and had made 10 life-size Lancaster bombers.[46] Fry said Wing Commander Guy Gibson's dog "Nigger" will be called "Digger" in the remake to avoid rekindled controversy over the original name.[47] For the remake, Peter Jackson has said no decision has been made on the dog's name, but is in a "no-win, damned-if-you-do-and-damned-if-you-don't scenario", as changing the name could be seen as too much political correctness, while not changing the name could offend people.[48] Further, executive producer Sir David Frost was quoted in The Independent as stating: "Guy sometimes used to call his dog Nigsy, so I think that's what we will call it. Stephen has been coming up with other names, but this is the one I want."[49][N 2] Les Munro, a pilot in the strike team, joined the production crew in Masterton as technical advisor. Jackson was also to use newly declassified War Office documents to ensure the authenticity of the film.[51]

After Munro died in August 2015, Phil Bonner of the Lincolnshire Aviation Heritage Centre said he still thinks Jackson will eventually make the film, citing Jackson's passion for aviation. Jackson said, "There is only a limited span I can abide, of people driving me nuts asking me when I’m going to do that project. So I’ll have to do it. I want to, actually, it’s one of the truly great true stories of the Second World War, a wonderful, wonderful story."[52]

In late 2018, news emerged that Jackson was to begin production on the film once again. He intended for production to commence soon, as he only had the film rights for "another year or two".[53]

• The attack on the Death Star in the climax of the film Star Wars is a deliberate and acknowledged homage to the climactic sequence of The Dam Busters. In the former film, rebel pilots have to fly through a trench while evading enemy fire and fire a proton torpedo at a precise distance from the target to destroy the entire base with a single explosion; if one run fails, another run must be made by a different pilot. In addition to the similarity of the scenes, some of the dialogue is nearly identical. Star Wars also ends with an Elgarian march, like The Dam Busters.[54] The same may be said of 633 Squadron, in which a squadron of de Havilland Mosquitos must drop a bomb on a rock overhanging a key German factory at the end of a Norwegian fjord.[55] Gilbert Taylor, responsible for special effects photography on The Dam Busters, was the director of photography for Star Wars.[56]
• In the 1982 film Pink Floyd The Wall, scenes from The Dam Busters can be seen and heard playing on a television set several times during the film. Particular emphasis is placed on scenes in the film where characters mention Nigger, Guy Gibson's labrador. "The reason that The Dam Busters is in the film version of The Wall," explained the Floyd's Roger Waters, "is because I'm from that generation who grew up in postwar Britain, and all those movies were very important to us. The Dam Busters was my favourite of all of them. It's so stuffed with great characters."[57] Waters had previously introduced the band's song 'Echoes' at live shows as 'March of the Dam Busters'.
• The 1984 video game The Dam Busters was partially based on the film.
• Two television advertisements were made for a brand of beer, Carling Black Label, which played on the theme of The Dam Busters. Both were made before the English football team broke a 35-year losing streak against Germany. The first showed a German guard on top of a dam catching a number of bouncing bombs as if he were a goalkeeper. The second showed a British tourist throwing a Union Flag towel which skipped off the water like a bouncing bomb to reserve a pool-side seat before the German tourists could reserve them with their towels. Both actions were followed by the comment "I bet he drinks Carling Black Label".[58] The adverts were criticised by the Independent Television Commission, although UK newspaper The Independent reported "a spokeswoman for the German embassy in London dismissed the idea that Germans might find the commercial offensive, adding: 'I find it very amusing'".[59]
