—Kevin Smith, on why he wanted to direct the film
In March 2009 it was announced that Kevin Smith signed on to direct a buddy-cop comedy starring Bruce Willis and Tracy Morgan (both of whom Smith had worked with on previous projects) called A Couple of Dicks and written by the Cullen Brothers, the first feature film Smith has ever directed, but not written. Prior to principal photography, Variety reported that the title had been changed to A Couple of Cops due to controversy surrounding the original one.. After negative reaction to the change, Warner Bros. recanted the story and reverted to the original title, though Smith denies that the original change was requested by the studio. In December 2009, the studio changed the title from A Couple of Dicks to Cop Out.
On December 9, 2009, Kevin Smith announced via his Twitter page that the film would indeed go by new title. He also stated that the first trailer for this film would be attached to every copy of Sherlock Holmes when it hits theaters on Christmas day. At the time, Smith acknowledged that the film is "not MY movie, [its] a movie I was hired to direct." 
The studio requested Smith to storyboard the entire film; Smith agreed, and he and Dave Klein, the director of photography, reviewed the results with Warner Bros. two months in advance. Filming began on June 2, 2009 in New York City and finished on August 14, 2009, for a February 26, 2010 release.
The first trailer for the film was released on December 23rd, 2009.
