Zapping every disaster movie cliché with the cartoon subtlety of Mad magazine may be nothing more than cannibal glee, but it prompts enough convulsions of laughter in this wacky spoof from the Kentucky Fried Movie team for you not to notice their dead hand at work. Imagine the same old '50s airplane yarn: pilots poisoned, passengers panic, while a traumatised war-hero lands the jalopy. It should be disastrous. But psycho ground controllers (Stack and Bridges), laff-a-second pace, and bludgeoning innuendo make this the acceptable face of the locker-room satire. DMacp.
