Westerns: The Searchers (original with John Wayne), Silverado, Tombstone.
Old War films: Run Silent, Run Deep, or Pork Chop Hill (probably the best and most accurate Korean War movie ever made). Lawrence of Arabia, Khartoum, The Guns of Navarone.
Classic films: Casablanca
Most newer movies are crap.
The Searchers is on TCM this evening.
We watched that last night on Turner Classic Movies.. It was outstanding in HD.!
