Entourage Sneak Peek: Matt Damon Cameo

On Sunday's night sixth season finale of Entourage, there's an Ari/Lloyd showdown.

There's also drama between Turtle and Jaime; and resolution to the ongoing E/Sloan drama.

But the episode is stolen by Matt Damon, who appears as himself and gets pissed at Vince's lack of committment to a charity he sponsors. It's great stuff. Watch Damon's cameo below:
