Not too many people know that the Zucker Brothers spoof Airplane! was "inspired by" another film called Zero Hour! (1957), but not too many people have seen that earlier film, directed by Hall Bartlett, based on a teleplay by Arthur Hailey (who would eventually write the novel "Airport"). YouTuber Mason Wood has done a meticulous job of cutting in between the two movies to show just how much Airplane! fed off Zero Hour! and it is very fun to watch.
