The Departed
starring Leonardo Di Caprio, Matt Damon, Jack Nicholson, Mark Wahlberg
Two young police detectives lives are intertwined - one is undercover in an organised crime ring, the other is infiltrating the police FROM the organised crime ring (with Jack Nicholson as the head honcho). Great story, a true "All Star" cast with excellent acting, and a good final quarter (with a high body count!).
