I'll add few more characters to my old and rather short post...

Riddick - by far the best role Vin Diesel has ever been in, one of my all time favorite anti heroes and sci fi characters in general. He lost certain amount of mystery around him in sequel to "Pitch Black" "The Chronicles or Riddick", nevertheless, he's still a pure badass.

The Joker - Heath Ledger's performance was simply stunning, he took role of the Joker to a completely new level making him what Jack Nicholson "failed" to do, cunning, insane, dangerous, but most importantly, Batman's worst nightmare.

Jason Bourne - perfect mix of James Bond and Jack Bauer, Jason Bourne is my all time favorite agent apearing in my all time favorite action movies. The scene with him on that Bosch building is something you don't easily forget.

Clint Eastwood - every one of his characters is usually epic to say the lest, though his appearance in western movies struck me the most.
