Muscle Beach Party

Funicello reprises her character from Beach Party, although in this film (and three others that follow) she is referred to as "Dee Dee", as opposed to "Dolores." John Ashley's character, previously called "Ken", is now known as "Johnny."[3]

Harvey Lembeck's Eric von Zipper character and his Rats gang from Beach Party are absent in this film, although they appear in Bikini Beach, Pajama Party, Beach Blanket Bingo, How to Stuff a Wild Bikini, and The Ghost in the Invisible Bikini. Lembeck as von Zipper (but sans Rats gang) also appears in a cameo in Dr. Goldfoot and the Bikini Machine. Lembeck also appeared in Fireball 500, another Avalon-Funicello vehicle, as an entirely different character. Peter Lorre appears briefly near the end of the film and there is a notice explaining that he will appear in the next installment of the series. Lorre died in March 1964; thus, this was his only appearance in the series.[4]

A 141-page paperback adaptation of the screenplay, written by Elsie Lee, was published prior to the release of the film by Lancer Books.

In the above-cited paperback adaptation, the Jack Fanny character introduces his bodybuilders as Biff, Rock, Tug, Riff, Sulk, Mash and Clod, whereas in the film he calls them Biff, Rock, Tug, Riff, Sulk, Hulk, and Clod. In two separate sequences, the latter version of these names is seen printed on their shirts.

Larry Scott, who played Rock, was well known in the bodybuilding world at the time and became the first Mr. Olympia. Due to his preference for a piece of gym equipment commonly known as the Preacher Bench,[5] the bench also became known as the Scott Curl Bench. Gene Shuey who played Riff, and Chester Yorton who played Hulk, were also well known in the bodybuilding circuit. Peter Lupus (aka "Rock Stevens") was also a champion bodybuilder himself, holding the titles of Mr. Indianapolis, Mr. Indiana, Mr. Hercules, and Mr. International Health Physique. He is best known as Willy Armitage, the strong, mostly silent, member of the IMF team in Mission Impossible from 1966–1973.[6]

The swimsuits were designed by Rose Marie Reid; Buddy Hackett's clothes were from Mr. Guy of Los Angeles; and the hat that Deadhead wears was designed by Ed "Big Daddy" Roth.

The surfboards used in the film were by Phil of Downey, California – aka Phil Sauers, the maker of "Surfboards of the Stars."[7] Sauers was also the stunt coordinator for another beach party film that used his surfboards, Columbia Pictures' Ride the Wild Surf, which was released later the same year. Sauers was even portrayed in that film as a character by Mark LaBuse.

The "globe" telephone cover on Mr. Strangdour's desk is the same one in Norma Desmond's home in the film Sunset Blvd.

The original score for this film, like Beach Party before it, was composed by Les Baxter.

Roger Christian, Gary Usher and Brian Wilson (of The Beach Boys) wrote six songs for the film:

• "Surfer's Holiday" performed by Frankie Avalon, Annette Funicello and the cast;
• "Runnin' Wild" performed by Frankie Avalon;
• "My First Love" and "Muscle Beach Party", both performed by Dick Dale and His Del-Tones;
• "Muscle Bustle" performed by Donna Loren with Dick Dale and His Del-Tones; and
• "Surfin' Woodie" performed a cappella by Dick Dale with the cast.

Guy Hemric and Jerry Styner wrote two songs for the film:

• "Happy Street" performed by Little Stevie Wonder; and
• "A Girl Needs a Boy" first performed by Annette Funicello, then reprised by Frankie Avalon as "A Boy Needs a Girl".

The colorful, hand-painted mural that is shown in full and in detail as background during the opening credits is by California artist Michael Dormer, whose surfer cartoon character, "Hot Curl" can also be glimpsed throughout the film.[8]

Although the end titles provide a credit reading, "Muscle Mao Mao Dance Sequence Choreographed by John Monte, National Dance Director, Fred Astaire Studios", no such sequence is found in the film's release prints.
