Trivia: Stay after the credits start rolling for a hilarious extra scene.
Trivia: Director Kevin Smith and star Bruce Willis infamously did not get along at all during production. Willis allegedly disagreed with Smith's recreational use of marijuana and didn't care for Smith's form of direction. Smith in return has called working with Willis "soul crushing", and has countered with claims that Willis refused to listen to direction, was often combative and sometimes refused to shoot scenes, would frequently yell at Smith and was generally unpleasant on and off set. Smith has said that working with Willis' friendly and open-minded co-star Tracey Morgan is what got him through the shoot.
Trivia: The original title was "A Couple of Dicks." (As "dick" was not only an old-time nickname for detectives, but is also obviously a reference to the male reproductive organ and is a common insult.) However, the studio got cold feet and worried the title would get them in trouble, so they decided to change the name to "A Couple of Cops." Director Kevin Smith told them that the new title was a "total cop out." The comment inspired Smith and the studio, who realised "Cop Out" would be a good title.
Answer: In his recent book 'Kevin Smith's Secret Stash', Smith states that he experienced "true darkness" working with Bruce Willis. According to Smith, Bruce Willis does not enjoy making movies. Smith accuses Willis of being lazy and accounts several stories of the two having creative differences on set, including Willis being angry that Smith allowed Tracy Morgan to improvise dialogue. Willis also apparently took issue with Smith contradicting him in front of the crew. For his part, Willis has only vaguely commented on the animosity between the two, calling Smith a "whiner" in one interview.
