The Glimmer Man (1996)
'Two good cops. One bad situation.'

Seagal is back to playing a New York cop here, though he gets transferred to LA to investigate some murders. His ex-wife is killed by the same murderer he is investigating (with the help of Wayans' character) and he must hunt down the killer and get his revenge! Note that the title of the movie deviates from the formula, however the poster features a big fat closeup of Seagal holding a gun (though the gun is blurry) and bonus points are acquired for the nice blue tint.
