If you want to see a good version of this? Then just watch The Last Boy Scout with Bruce Willis and Damon Wayans...which IS a classic.
Cop Out is a 2010 American buddy cop comedy film directed and edited by Kevin Smith, written by Mark and Robb Cullen, and starring Bruce Willis, Tracy Morgan, Kevin Pollak and Seann William Scott.
The plot revolves around two veteran NYPD partners (portrayed by Willis and Morgan) on the trail of a stolen, rare, mint-condition baseball card who find themselves up against a relentless, memorabilia-obsessed bloodthirsty gangster. This is the first film that Smith directed that he did not also write.
Upon its release, the film was met with negative reviews by critics and underperformed at the box office.
