Kelly's Heroes and Where Eagles Dare are great films. Fun to watch. Staying with Clint, you can't forget "Dirth Harry", one of the coolest movie characters ever!
I find that most of today's action movies are way too predictable and frankly a little boring. Most of them don't really stand out and are usually forgotten fairly quickly. I'll take "Dirty Harry", "Death Wish" or "Night Hawks" anyday. Saying that however, I'll always have time for some 80's action cheese like "Cobra" or "Highlander"
