I can understand DeNiro wanting to do comedy but Pacino's roles make no sense to me. Apparently his new movie (88 Minutes) is absolutely horrible, and both will be in a sucky movie with 50 Cent sigh.
Seems like they aren't being challenged, perhaps because they don't respect the directors they work with. Clearly they have a sense of entitlement. If DeNiro were to do another film with Scorsese I bet he'd give a great performance, in part because he'd feel challenged
