Carnival of Monsters

The TARDIS misses Metebelis Three and materialises on the SS Bernice, a ship that suddenly disappeared while travelling the Indian Ocean. Being repeatedly arrested as stow-aways, the Third Doctor and Jo find out that ship's occupants keep repeating their actions, having no recollection of earlier encounters. The pair escape from the ship through a strange hatch plainly visible to them both but ignored by the crew and passengers. The Doctor and Jo venture through the circuitry of some sort of giant machine and arrive at marsh lands.

They soon discover that they are not outside but are still inside the machine. Chased by Drashigs, huge swamp-dwelling carnivores, they escape back into the circuitry. Here, the Doctor realises that they have materialised inside the compression field of a Miniscope, a machine that keeps miniaturised groups of creatures in miniaturised versions of their natural environments. The Time Lords have banned such machines, but apparently one escaped. The Drashigs break into the circuitry and the Doctor and Jo flee back to the ship. They are separated in the confusion as the crew defend against the Drashigs.

The events inside the miniscope are intercut with events involving its owners, travelling showman Vorg and his assistant Shirna, who have just arrived at the planet of Inter Minor but are suspected of being spies and refused entrance by a tribunal. The tribunal learns that objects removed from the machine soon return to their normal size when Vorg extracts a foreign object stuck in the circuitry – actually the TARDIS – from the machine. Two of the tribunal members, dissatisfied with the leadership of their planet, plot to let the Drashigs escape from the machine and allow them to wreak havoc, causing a crisis and the president's resignation.

The Doctor eventually finds a way to the real outside and is restored to normal size. He cooperates with a reluctant Vorg to return into the machine by linking it with the TARDIS. After he goes back into the Scope, which is now overheating due to the Drashigs' damage, the device he attached is shot by a tribunal member and ceases to function, leaving the Doctor stranded. He finds Jo, but they collapse on the floor as the heat gets to be too much for them.

Two Drashigs escape, but Vorg kills them by fixing the eradicator, sabotaged by the mutinous tribunal members. He fixes the Doctor's device, pushing the Phase Two switch which brings the Doctor and Jo back, just in time, and also returning all of the Scope's other occupants to their rightful space-time positions.

As the penniless Vorg tries to get enough credit bars to return home by using the old three-magum-pods-and-a-yarrow-seed trick, the two travellers depart in the TARDIS.

Working titles for this story included Peepshow. This story was recorded as part of the production block for the previous season but deliberately held over for Season Ten. This was to enable Barry Letts to direct the production, since his role as producer would have made it difficult to do so at the start of a production block (as he had found out with Terror of the Autons).

The titles for Carnival of Monsters were prepared, like Frontier in Space, with a new arrangement of the theme music performed by Paddy Kingsland on a synthesizer. Known as the "Delaware" arrangement (the BBC Radiophonic Workshop was based on Delaware Road), it proved unpopular with BBC executives, so the original Delia Derbyshire theme was restored, and only appears on an uncorrected version of episode two that was shipped to Australia in error. This edit, which also featured a few extra scenes, was used in the 1995 VHS release. (The opening and closing title sequence versions of the theme have been included as an extra on the DVD release of the story. The original 2m 30sec theatrical release of this music was wiped many years ago.)

The ship used was the RFA Robert Dundas which had been decommissioned and was scrapped immediately after filming. As the ship was actually in transit on its final voyage down the River Medway in Kent all external shots had to be filmed at a low angle or the banks of the estuary would have been visible.[2]

When the serial was repeated on BBC2 in November 1981, daily, Monday-Thursday (16 November 1981 to 19 November 1981), at 5.40pm as part of "The Five Faces of Doctor Who", Barry Letts (then the series' Executive Producer) requested that the last few moments of episode 4 be edited to remove a shot where actor Peter Halliday's baldcap had slipped. The ratings for the repeats were 4.9, 4.5, 5.6 & 6.0 million viewers respectively.[7]

In 2010, Mark Braxton of Radio Times wrote that "the premise is ingenious" and "[furnished] with rich, imagination-kindling fare". He praised the guest cast, though he felt the Drashigs were a mixed bag.[8] DVD Talk's John Sinnott gave the serial three and a half out of five stars, describing it as "light and fun" and praising the Miniscope and guest actor Leslie Dwyer.[9] Neela Debnath of The Independent wrote that Carnival of Monsters had a "well-crafted plot that keeps the audience guessing for quite a while and this suspense serves as the driving force behind the serial". She felt that the Drashigs still worked because they were "such hideous-looking creatures".[10] On the other hand, IGN reviewer Arnold T. Blumburg named the serial one of the worst of the Pertwee tenure, stating that it had "the most appalling character, set, and costume design in the era's history" and that some of the guest actors were wasted.[11] In 2013, Den of Geek's Andrew Blair selected Carnival of Monsters as one of the ten Doctor Who stories that would make great musicals.[12]
