We've often thought that films like The Towering Inferno or The Poseidon Adventure remake had a real chance of being great — if only they'd been comedies. Fortunately, the makers of Airplane! had this same idea — and, like most of their gags, took it one step further. Nabbing the basic plot and portions of the dialogue from a 1957 disaster film called Zero Hour!, they created what's surely one of the most gloriously turbulent satires ever. Just don't call it…you know.
