I agree that Clint made the best cowboy flicks. But like you said....He's a little on the old side. The newer ones aren't that great. 3:10 to Yuma is okaaaaay, so are a couple others. But not good enough to stick in my mind.
The Dark Knight is a good flick, so are Iron Man, The Hulk, Hancock, Tropic Thunder (more of an Action/Comedy)
Death Race is a remake, but actually a REALLY good one! "Babylon AD" is a Sci-Fi/Action Flick, and another good one.
The "Transporter" series is pretty good too. Comming out next month is yet another remake (supposedly pretty good too!) is "The day the Earth Stood Still"
If you haven't seen it, then the remake of "War of the Worlds" with Tom Cruise is another one of my favorites.
"Valkyrie" with Tom Cruise is also REALLY good! I saw a 35 minute pre-release teaser with some friends of mine. It's about a group of German Officers that plot to assassinate Hitler.
