Trivia: Director Jim Abrahams has two roles in this movie. The first role was that of the bicycle rider that yells back at Kramer after Kramer hits him on the road. He also plays a role as a solicitor at the airport. He is the one who pauses after seeing how Kramer is treating the other solictors.
Trivia: While the film is a parody of many of the 70's disaster movies, including the Airport film series, it's mainly a parody of the film Zero Hour! In fact, the creators bought the rights to the screenplay Zero Hour! and kept many of the plots and character names, and even dialog. Arthur Hailey who wrote Zero Hour! also wrote the Airport series.
