Trivia / Happy Birthday to Me

  • Dawson Casting: 25-year-old Matt Craven as one of many 20-something teens.
  • Executive Meddling:
    • The DVD was butchered when it first came out: a bland computer graphic of a girl with a birthday cake (and a castle being shown outside the window) was used because the studio felt no one cared about 80s slasher films and wanted to trick people into thinking it was a new Direct-To-DVD film instead. They also haphazardly used a different print which had a completely different soundtrack, one that was used as a placeholder while the real one was being finished. They later fixed these things when the film was re-issued by Anchor Bay several years later. Mill Creek Entertainment's Blu-ray release (in a double feature with When a Stranger Calls) leaves the original film intact as well.
    • Some of the kills in the film were trimmed down to avoid an X-rating. Most notably, the motorcycle and weight-lift kills.
  • Star-Derailing Role: The film killed Melissa Sue Anderson's career. Fresh off the success of Little House on the Prairie, her starring in a B-list slasher flick must not have looked too good on a resume, as her career ever since has been filled with nothing but D-list projects at best.
  • Throw It In!: The director wasn't happy with the original scripted ending where Virginia simply turns out to be the killer and the twist ending was come up with in the spot.
  • What Could Have Been: According to an interview with Lisa Langlois, her character Amelia was originally killed off. In the first cut of the film, her character got an axe to her head. Langlois was told by David Douglas (a cameraman on the set) that the film would have been rated X if they kept that scene intact. So instead, the producers decided to make her look like the sole survivor in the final release.
    • In a 2011 interview with the website The Terror Trap, producer John Dunning revealed he had discovered a box of some kill scene cuts that were made for the Canadian film board. His plan was to put the trims together, compare it to the U.S. release to see what’s missing, and try and get Columbia to put the missing cuts back in. Unfortunately, nothing seemingly came of it and Dunning would pass away that same year.
  • Writing by the Seat of Your Pants: Among other things, the Twist Ending was written into the film after production began. They had already filmed Ann's death scene by the time they informed her actress that she was now playing the killer.
