The astute film buff (and anyone who owns the Airplane! DVD) knows that the modern comedy classic Airplane! was largely based on the 1957 film Zero Hour. As a rabid fan of Airplane!, I've always been on the lookout for a late-night screening of Zero Hour, but have never been able to catch one. To my knowledge, it's never been released on video at all. I'm curious to see how closely the "source material" resmbles my beloved spoof. Who's seen this flick?
