Don't let the reviews scare you away: this isn't just a movie about jiggling girls. There's a lot of beefcake for the guys to look at, too.
Good teenager Tommy Kirk, recently outed and evidently taking any role, no matter how feeble, is the putative star, trying to stop a group of evil teenagers from running rampant in his small fifties town. His job is made harder when they ingest something called "goo" that makes them grow to giant size.
Now comes the part of the movie that everyone fast-forwards to: the evil teens are naked at first and then they wear makeshift togas, the boys displaying beautiful, athletic bodies, as they dance in slow motion in the town square. The female teenagers are all but ignored as director Bert I. Gordon (who had a keen eye for beefcake) lingers on the gorgeous Beau Bridges and Tim Rooney (Mickey's son), who is not quite as gorgeous but makes you wish he had appeared in more movies (or at least a centerfold or two).
The boy on the giant breast that everyone keeps mentioning is teen idol Johnny Crawford, recently graduated from "The Rifleman" and soon to display a magnificent physique of his own in "The Naked Ape"; but he's not dancing or being hugged, he's attempting to destroy the giants by catapulting at them with the antidote to the "goo."
The writers should have created a more logical, suspenseful plotline, or else they should have eliminated all pretense at a story and just had Beau Bridges, Tim Rooney, Johnny Crawford, and Tommy Kirk pose in swimsuits for 90 minutes. But it's worthwhile reminding ourselves that directors were making movies for guys long before "Risky Business."
