In the wake of the success of its first Beach Party movie, released in the summer of 1963, American International Pictures greenlit two sequels in quick succession, both also directed by William Asher. The reason they’re of interest to this site is because both feature random cameos by wolfmen that have no bearing whatsoever on their plots, but that’s par for the course with these movies, which exist solely to string together six to ten musical numbers and a handful of surfing montages. While the first movie starred Robert Cummings and Dorothy Malone (as a tweedy anthropologist and his secretary), the sequels were top-billed by Frankie Avalon and Annette Funicello, who play the surf-crazy Frankie and his long-suffering sweetheart Dee Dee, respectively.
Always surrounded by a gaggle of beach boys and girls (some of whom were fixtures of the series, like John Ashley and Jody McCrae), Frankie and Dee Dee are far from the most harmonious couple — she’s always pushing him to improve himself and think of the future, he’s content to keep living in the moment — but they’re the closest thing these movies have to a stable relationship. They also have to weather a variety of outside antagonists, most frequently contending with oafish biker Eric Von Zipper (Harvey Lembeck) and his gang, the Rat Pack. They’re nowhere to seen in 1964’s Muscle Beach Party, though, which is fine because Frankie, Dee Dee, and their gang have enough on their plates as it is.

First there’s a group of body builders managed by gym owner Jack Fanny (Don Rickles), who moves them into the beach house next door. Another wrinkle is the Italian contessa (whose long-suffering business manager is played by Buddy Hackett) who turns Frankie’s head and threatens to break up the happy couple for good. So where does the werewolf figure in, you ask? Well, Jack Fanny has a silent partner named Mr. Strangdour (played by Peter Lorre), and he has a secretary named Igor who lacks hair on his hands, but has enough enough fuzz on his face to get my attention for the scant seconds he’s onscreen. (Igor has no lines apart from some growling, and his one action is to pick up a ringing phone and pass it over to his boss, who proceeds to pulverize it because he’s the world’s strongest man.)
Following the precedent of its predecessor (which featured Vincent Price in a minor role), the end credits tease that Lorre was “soon to return in Bikini Beach,” but that was not to be since he died just four days after Muscle Beach Party‘s spring release. In his stead, fellow horror icon Boris Karloff stepped in to play an art dealer interested in the action paintings of Big Drag (Rickles again), who owns the hangout where the gang likes to hang out when they’re not catching waves, as well as the drag strip that is the focus of the action when Frankie finds himself in competition with an insufferable British pop star called the Potato Bug (an obvious swipe at the Beatles, also played by Avalon) for Dee Dee’s affections. He’s not the only impediment to their happiness, however, as local bigwig Harvey Huntington Honeywagon III (special guest star Keenan Wynn) aims to make a monkey out of the teenage contingent that has descended on his beach community with the assistance of his trained chimp Clyde. His editorials inspire the unwanted adoration of Eric Von Zipper, though, which gives Honeywagen his first inkling that he may be on the wrong side.

Also on the wrong side, at least based on the company he keeps, is The Teenage Werewolf Monster, who appears 68 minutes in and hangs out in the background at the Rat Pack’s hangout while Von Zipper shoots pool with South Dakota Slim (Timothy Carey, who returned as the character in Beach Blanket Bingo). Decked out in a black leather jacket, having apparently graduated from high school, this Teenage Werewolf Monster even clutches a glass of milk in his paw (an oblique reference to the original), but doesn’t drink from it. And he’s conspicuously absent when the requisite brawl breaks out at Big Drag’s. Must be why he wasn’t asked to come back for the sequel.
