Everything About Fiction You Never Wanted to Know.

Karla is a 2006 American psychological thriller film, based on the true story of two of Canada's most notorious serial killers, Paul Bernardo (Misha Collins) and Karla Homolka (Laura Prepon).

Tropes used in Karla include:
  • California Doubling: An extreme case of it, as the movie was set in Canada but shot in America with an all-American cast (Laura Prepon played Karla) because no one in Canada wanted anything to do with the production.
  • Character Title
  • Old Shame: Misha Collins has stated many times that he regrets his participation in Karla. He has explained that he was unaware how infamous and emotionally relevant the cases were in Canada at the time, and also states that the director of the film took things way too far and would compliment him after shooting particularly horrible rape scenes, saying "That was hot." He ended up having a phone conversation with one of the victims who escaped, and now tells people not to watch the movie, especially when it comes up at fan conventions.
  • Ripped from the Headlines
  • Very Loosely Based on a True Story: The story itself is (sadly) quite true to reality, but mistakenly portrayed Homolka as yet another victim of Bernardo's sociopathic antics - despite the fact that it's long-since been established that she was just as culpable as Bernardo. The Canadian media and public were understandably appalled.
