Re: The Departed
DiCaprio is a brilliant actor.
As far as who gave better performances and what not, I think a lot of it has to do with the fact that these actors got written some great characters as well. Not to take anything away from their acting chops, because I think all of them gave standout performances in this film. And as good as Wahlberg was, he had some great writing behind his character. Hell, Wahlberg probably had a lot of the most memorable dialogue of the film.
Either way, I do think that Wahlberg and Nicholson gave the strongest performances in the film writing or not. Wahlberg stole just about every scene he was in.
