GoGo (Tommy Kirk), a somewhat incompetent Martian agent, is sent to infiltrate Earth's teenagers in anticipation of an invasion from the Red Planet. Needless to say he promptly falls for Terran tart Connie (Annette Funicello, whose Disney-mandated bathing-suit is the most demure on the beach). This sci-fi-comedy, the fourth in AIPS popular 'beach' series, is full of scantly-dressed, energetically dancing youngsters (including a youthful Terri Garr), spontaneous singing, slapstick yucks, a touch of meta-humour (usually referring to the 'absent' Frankie Avalon), and an interesting secondary cast including silent-movie icon Buster Keaton (as Indian chief Rotten Eagle, a role that these days would be considered near blasphemous cultural appropriation, "Ugh!"), Dorothy Lamour (the sexy sarong-clad sidekick from the "Road to..." series) who has the best musical number (asking the classic generation-gap question 'Where Did I go Wrong?') and the lonely Maytag repairman himself, Jesse White, as the ridiculously named 'J. Sinister Hulk'. The barely existent plot makes little sense and serves primarily to set up comedic or terpsichorean set-pieces. The film also features the great Elsa Lanchester as a wealthy but ditsy dress-shop owner and a number of the usual beach-movie crowd (including Mr. Warmth himself, Don Rickles as 'Big Bang' a disgruntled Martian and Harvey Lembeck's brainless-biker Eric Von Zipper). The first part of the film is amusing in a goofy way but the story soon degenerates into a lengthy, time-killing, chase-sequence before climaxing at the titular party, a silly and not particularly funny series of predictable sight-gags and faux-teenage shenanigans. The 60's go-go style dancing is fun to watch but other than Lamour's song, the music (especially Annette and Tommy's duet) is unmemorable. Needful watching for all fans of beach movies and for obsessive sci-fi completists, otherwise, OK fluff for anyone in the mood to get nostalgic for a kinetic 1960s than never really existed. Kirk returned to Earth as a Martian in Larry Buchannan's penurious but evocatively entitled time-waster 'Mars Need Women' (1968).
