This is a really tough one and perhaps the result will be totally different when i think about it nest time, but here are three of my favourites:
The Great Escape (all-time classic from 1963, i end up watching it every time it's on TV)
Tiger and Dragon (great martial arts, packed in beautiful pictures)
Miami Vice (gotta have a movie with some action, and i just love the atmosphere of the outside night scenes)
Edit: Just remembered, 'Tiger and Dragon' is just the german title (logic?), most of you will know it under 'Crouching Tiger, Hidden Dragon'
