The reason for this is because the ZAZ team framed their zaniest conceits (having Barbara Billingsley trade jive with two unreceptive African-Americans, sparking a ferocious, furniture-smashing barroom brawl between two Girl Scouts, undercutting a scene of plane cabin panic by having a big-breasted woman run in front of the action for a single jiggly second) with an uncredited, scene-for-scene fabrication of a forgotten ‘50s airplane actioneer called Zero Hour (based on a novel by Airport author Arthur Hailey).
