One of those kitsch 1960s Californian beach party movies which began with Beach Party (1963).
In this one, Tommy Kirk plays a Martian scout sent to Earth to prepare for an invasion who drops in on the high jinks of a teenage party with suitably nonplussed results.
Meanwhile, a plot is afoot by two con men to steal the hostess’s money. The Martian falls in love with one of the girls at the party, thwarts the robbery and calls off the invasion.
It is meant to be gently amusing but is unintentionally gut-wrenchingly funny, despite the presence of such greats as Buster Keaton and Dorothy Lamour.
Watch out for bit parts from 1980s one-hit wonder Toni Basil and 80s comedienne Teri Garr.
