Trivia: When Dustin Hoffman and Gene Hackman have their showdown in the lavatory towards the end, Hackman greets him and says that this is a "long overdue pleasure." This is a reference to the fact that this scene is the first scene ever between Hoffman and Hackman, two former classmates at film school, in their substantial screen careers. Despite being in the industry for decades, and being long-time friends, they had never made a movie together.
