First off, Zombieland, Woody harrelson does a great job as a crazy man who loves to kill zombies. The best line in the movie to me is probably, "Nut up or shut up." My one problem with the movie was that a little girl, (Abigail Breslin) and her older sister, (Emma Stone) rob them twice, and BOTH times, Woody Harrelson and his assistant, Jesse Eisenberg go to help them.
Second, there is the classic movie, Die Hard, Die Hard is the perfect movie for someone who wants to watch one man take on dozens of terrorists, barefoot, with limited ammo.
Also how can you forget Rambo, released in 08, this is probably the most violent movie I have ever seen. I mean, he tears a guy's throat out! That's one of those movies that is just fun to watch when you are real bored!
