Pitt--Smith is very likable but he doesn't seem to have much range. not that Pitt has much more
Spielberg--hard because Coppola has put out a few great movies, but the sheer number of good to great movies Spielberg has done rules it. plus he invented the summer blockbuster and the modern action movie
Hanks--acting abilities are similar but Hanks has put out more good movies
Nicholson--Pacino is entertaining, no question, but nicholson is still a better actor.
DeNiro--again, I think their acting abilities are similar but Deniro has put out more great performances and more good movies
Jolie--she's capable of great depth (Girl, Interrupted), Jones doesn't seem to be much more than pretty actress with good charisma
Norton--after a while, I just can't get past the unfortunate fact that DiCaprio is a world class actor stuck in the body of a back-street boy.
Eastwood--love Cary Grant but he played the same character over and over, and it wasn't all that an interesting a character to begin with. i know some people argue Eastwood does the same thing, but I disagree. plus, his characters have a lot more depth
Peter Jackson--I'm crazy about Christopher Nolan, but as great as The Prestige, Memento, and Batman are, they don't measure up to the accomplishment of bringing LOTR to the screen in the way Jackson did
Hitchcock--Scorses makes good, sometimes great movies, but I usually rate his movies lower than other people. Hitchcock created the psychological thriller
Daniel Day Lewis--big fans of both, but gotta give the edge to Lewis. he just seems to disappear a little further into the role
Ford--Connery is definitely likable, and everybody loves him as Bond, but he's played in a bunch of junk. Ford at least tries to play somebody other than the same guy every once in a while
Tarantino--Scott makes great films, but Tarantino is more inventive
Williams--Spacey plays the same wise-@$$ over and over. it grates after a while. Williams usually plays a manic, but every once in a while he steps outside his comfort zone. and when he doesn't, he's almost always entertaining.
