Airplane! (1980). The comedy team of David Zucker, Jim Abrahams and Jerry Zucker struck gold when they found the script of a 1950s airplane thriller called Zero Hour. Taking the old script about a guy who gets on a plane to chase his girlfriend and then winds up being talked through the landing by his old army sergeant as inspiration, all the writers had to do was add jokes. The line, about finding somebody aboard the plane who didnt have fish for dinner was in both films.
