Bruce Willis would be starring as a troubled cop in "16 Blocks" for his buddy, "Lethal Weapon" director Richard Donner.

The film tells the story of a New York police department officer who's forced to take a happy, but down-on-his-luck witness 16 blocks from the police station to 100 Centre Street, although no one wants the duo to make it, reports the Hollywood News portal.

The story, whose filming will start April in Toronto, is said to be a redemptive tale for the characters who are polar opposites - the cop, a dark guy with a heart attack waiting to happen and the witness, a 14-time loser with a sunny outlook.
