De Niro, Pacino and Pesci have been in a combined total of about five decent movies in the last twenty years. Until I see the movie I will reserve judgement, but I'm not going to assume it's going to be good just because of their involvement. The positive thing is that Scorsese's output has remained solid and I don't think he'd attach himself to something if it didn't have promise.
I will see your De Niro, Pacino and Pesci and raise you the guy from Everybody Loves Raymond.
