Falling Down is a 1993 drama-thriller film that follows a disgruntled and unhinged man named William "D-Fens" Foster (played by Michael Douglas) as he goes on a violent rampage across Los Angeles. In other words, it's basically a day in the life of an average LA commuter. Foster's quest to reach his daughter's birthday party takes a dark turn as he encounters various characters and situations that push him over the edge.
