Matt Damon is filming Adrian Grenier in what appears to be a PSA for some legit company. Adrian seems to have trouble and trips up his lines quite a few times. Damon, after a few minutes of correcting him just snaps! Jeremy Piven is behind the camera with Matt, which is leading people to speculate it may be a setup for a scene in Entourage… But see for yourself. It is WAY to realistic anger to be acted. Matt Damon is a great actor…But this great? I hope it isn’t real, I had alot of respect for him as a non-Hollywood Douchebag.
