What do you get when you mix the children of famous Hollywood actors (Beau Bridges, Tisha Stirling and Tim Rooney), a couple of former child stars (Tommy Kirk and Johnny Crawford), a then current child star (Ron "Ronny" Howard) and a future one hit wonder (Toni "Micky" Basil) with a hack director (Burt I. Gordon). You get one of the biggest camp classics in the history of film. This film attempted to mix the then popular beach party flicks with the fading giant human pics. Gordon must have really been desperate for a hit because he figured that if he couldn't get Lloyd Bridges, Ann Southern and Mickey Rooney he could at least get their children to play in one of his quickie drive-in movie features. It's fun if you like camp, but as far as a great film, I'll stick with the films this mess rips off.
