Trivia / Eternal Sunshine of the Spotless Mind

  • Advertised Extra: Kirsten Dunst is in way less of the film than the marketing campaign made it out to be.
  • Deleted Role: Ellen Pompeo initially appeared in the film as Joel's ex girlfriend Naomi, who is only mentioned in the final cut. A subplot would have had Joel having a one night stand with her.
  • Deleted Scene: In the extended version of Mary's tape, we learn that Mierzwiak pressured Mary into having an abortion as well as a memory wipe.
  • Enforced Method Acting:
    • When Stan scares Mary, Mark Ruffalo was instructed to hide in a different place each take to actually scare her.
    • Clementine punches Joel in the train scene. Kate Winslet actually hit Jim Carey, and his reaction is real.
  • Fake American: Kate Winslet and Tom Wilkinson are both British actors playing New Yorkers.
  • Misaimed Marketing: The Italian release had a misleading title - translating as "If you leave me, I deleted you" - and many Italians went into the movie expecting a comedy.
  • Playing Against Type:
  • Throw It In:
    • A scene length one. While filming in downtown Manhattan, they heard that there was a circus parade going on outside. Gondry grabbed a portable camera, and got some footage of Carrey and Winslet messing around in the crowd completely anonymous due to it being night time and since the actors were wearing winter gear. The result is one of the happier memories in the movie.
    • Stan and Mary dancing over the unconscious Joel in their underwear was improvised.
    • The voice whispering "Mantauk" is a combination of Kate Winslet's voice and an editor working at Focus Features. The woman was asked to do a quick voice over before Kate Winslet arrived, and they left it in.
  • Viral Marketing: A website for Lacuna Inc. was created to promote the film. It contained a link to watch Joel experience the procedure, which would link to the movie's official website.
  • What Could Have Been: Besides Mary's deleted subplot and the additional ending mentioned below, there was to be a montage of people who wanted their memories erased - a soldier seeing his dead friend on the battlefield and a girl who had been raped at a young age.
  • Word of God: In an alternative script there's an extra ending, where an older Clem goes back to Lacuna to erase Joel again, and an older Mary reveals to her that Clem and Joel have been erasing and re-erasing each other for years, always ending up back together.
