Here are some I can think of off the top of my head -
I always liked the Sergio Leone/Clint Eastwood movies, A Fistful Of Dollars, For a Few Dollars More, The Good, The Bad, and The Ugly, as well as some of the Eastwood movies that came after.
For newer movies, I really enjoyed the Lord Of the Rings trilogy. In my opinion they could have even made it even longer, or in more parts, in order to include a lot of the stuff they left out. I've read the books at least 3 or 4 times since I was young and the movies followed them pretty well.
I also liked the Blade movies... martial arts and vampires, always a good combination !
