Fargo 1996

It is fiction - it's not based on a true story.

My bad ppawel. I stand corrected.

Fargo opens with the following text:
“ THIS IS A TRUE STORY. The events depicted in this film took place in Minnesota in 1987. At the request of the survivors, the names have been changed. Out of respect for the dead, the rest has been told exactly as it occurred. ”
Although the film plot is completely fictional, the Coen brothers claimed that many of the events that take place in the movie were actually based on true events from other cases that they threw together to make one story. Joel Coen noted:
“ "We weren't interested in that kind of fidelity. The basic events are the same as in the real case, but the characterizations are fully imagined ... If an audience believes that something's based on a real event, it gives you permission to do things they might otherwise not accept."[5] ”
The Coens claim the actual murders took place, but not in Minnesota.[6] The main reason for the film's setting is the Coens were born and raised in St. Louis Park, a suburb of Minneapolis.[7]
On the trivia track of the film's special edition DVD, it is revealed that the main case that inspired the movie is the infamous 1986 murder of Helle Crafts from Connecticut at the hands of her husband, Richard, who disposed of her body through a wood chipper.[8] The end credits bear the standard "all persons fictitious" disclaimer for a work of fiction.
