"All actors do that. Should do that and do that. For the most part. I say all actors. I'm exaggerating, but you know who does and who doesn't. Vince is a wonderful young actor who knows his work and did a beautiful job on this film"

Harvey Keitel is applauding Vince, a young actor, for his deal with a movie. He is indicating that all actors must make every effort to do their finest work, which Vince is an example of somebody who does. He is likely describing the devotion and effort that goes into being a successful star. He is likewise likely exaggerating when he says "all stars," as it is impossible for every single star to be as dedicated and hardworking as Vince. Keitel's words are a testimony to Vince's talent and devotion, and work as a support to other actors to pursue quality in their craft.
