The Last Shot (2004) on Netflix

Straight shooter agent Joe Devine has been assigned to cook up an elaborate scheme to take down infamous mob boss John Gotti. He assumes the role of a Hollywood producer and tells all the right lies to enlist a stooge to help execute his sting. He finds unsuspecting wannabe director Steven Schatz, who'd do just about everything to get the chance to direct a feature. Schatz falls hook, line, and sinker for the pitch, but what Devine doesn't tell Schatz is that the movie will never be made. Everything goes according to plan - until Devine and the suits at the Bureau start enjoying their new lives as Hollywood players a bit too much.
