Trivia / National Lampoon's Christmas Vacation

  • Defictionalization: People drink eggnog from the bowl in Walley World moose cups. You can buy them.
  • The Other Darrin: Russ and Audrey, as usual. Audrey somehow managed to age at a much faster rate than Russ since the first movie as well....
    • Though in the sequel, Audrey is once again played by Dana Barron who played her in the original 1983 film.
  • Playing Gertrude: Diane Ladd, who plays Clark Griswold's mother, Nora, is actually less than eight years older than Chevy Chase. In fact, Chase is closer in age to Ladd than he is to Beverly D'Angelo.
  • The Red Stapler: Quite a few items from the movie (like the Walley World eggnog glasses) are popular Christmas items and Clark's Blackhawks jersey (seen in the "Shitter was full!" scene) is popular with Chicago Blackhawks fans. It's not uncommon to see the occasional white Hawks jersey customized with Clark's name and "00" number on the back.
  • Throw It In!: After failing to get the Christmas lights to work one last time, Clark Griswold takes his frustration out on the plastic decorations in the front yard. Chevy Chase actually breaks his pinky finger while punching Santa Claus. He resorts to kicking and clubbing the decorations after that. The film kept rolling and the take was used.
  • What Could Have Been: According to an article on the making of Home Alone in Chicago Magazine, Chris Columbus states that he was the original director of this movie. Although he filmed some second-unit establishing shots (which he claims are still in the finished film), he left after two meetings with Chevy Chase and told John Hughes, "There's no way I can do this movie. I know I need to work, but I can't do it with this guy." He was sent the script to Home Alone in its place.
  • You Look Familiar: Clark's boss is played by Brian Doyle-Murray, who appeared in National Lampoon's Vacation as a hotel clerk.
