Fargo is the Coen Brothers movie that had everyone going around saying "dontcha know" and "you betcha!" for a while way back in the mid-90s, and it's so highly regarded that it was inducted into the U.S. National Film Registry for being "culturally significant."
It's one of those rare multi-genre movies that actually works, and watching this making-of documentary made me love Fargo even more than before.
