Your Mom

How am I the first to type that?

Richard Widmark or Robert Mitchum.

Not that I have any overblown adoration for the gentleman, but Christian Bale always seems to pick great movies to do.

Ben Stiller

I will see, and for the most part have seen, anything with Johnny Depp. (The exception being Platoon, which I own but haven't gotten around to watching, and some smaller roles.)

Also on the list, I'll usually see anything with these actors:
Brad Pitt
Tom Cruise
Robert Downey, Jr.
Edward Norton
Paul Giamatti
Shia LeBouf
Ryan Reynolds
Will Smith
Morgan Freeman
George Clooney
Al Pacino
Christian Bale
Gary Oldman
Michael J. Fox
Leonardo DiCaprio
Tom Hanks
Jim Carrey
Billy Crudup
Hugh Grant

Oh, why bother? The list goes on. I see a lot of movies.

As far as actresses go, mainly Winona Ryder, Kirsten Dunst and Scarlett Johannson, because I am in love with all of them. Hardcore.

It's weird because I used to avoid Brad Pitt and Tom Cruise until I saw them both in Interview With The Vampire and then managed to see every major movie they were in in the theatre since that was released until the year Troy and Collateral came out. I believe that was the same year too. I missed them both, although I did eventually see the latter, and will eventually see the former.

I absolutely agree with the first one. After his performances in Gangs Of New York and There Will Be Blood (which are NOT the same), I am very tempted to check out some of his other work.

The thing about Denzel though is this, and it never fails: I see a trailer for a movie he's going to be in, and I'm like, "Oh, that looks good, I want to see that." Then I never do. The last movie of his I saw in the theatre was John Q., although the trend started with Training Day and The Hurricane (I did eventually see the former). I'm pretty sure I've wanted to see every single movie he's been in since when I see the trailer, but for some reason, I just never do. I thought it would change last year with American Gangster, but it still didn't. Go figure.
