I’m declaring formal shenanigans on this question.  I can’t even name my favorite character of certain actors.  So I’m just going to do a running list because there are way too many to try to list and then explain why.  I know I’ll miss some, but here are a bunch:

Tyler Durden (Fight Club)
Seth Gecko (From Dusk Till Dawn)
Frank Drebin (The Naked Gun)
Quint (Jaws)
Brodie Bruce (Mallrats)
Han Solo (Star Wars)
Jack Burton (Big Trouble in Little China)
John McClane (Die Hard)
Tony Stark (Iron Man)
Indiana Jones
Fast Eddie Felson (The Hustler)
Doc Holiday (Tombstone)
Mr. Pink (Reservoir Dogs)
Irwin M. Fletcher (Fletch)
Ellis “Red” Redding (The Shawshank Redemption)
Ivan Drago (Rocky 4)
Morpheus (The Matrix)
Fenster (The Usual Suspects)
Jonathan Doe (Se7en)
Ash (Evil Dead 2)
Lester Burnham (American Beauty)
Buffalo Bill (Silence of the Lambs)
Stanfield (Leon aka The Professional)
Bud White (L.A. Confidential)
Gunnery Sgt. Hartman (Full Metal Jacket)
Walt Kowalski (Gran Torino)
Jeffrey “The Dude” Lebowski (The Big Lebowski)
Bill the Butcher (Gangs of New York)
Butch Cassidy (Butch Cassidy and the Sundance Kid)
Captain Malcolm Reynolds (Serenity)
The Joker (The Dark Knight)

And the list can go on and on…I’m just tired of thinking and typing.  If you haven’t seen any of the movie listed above, you should.
