You know the ones. Your channel surfing and a movie pops up that you just stop to watch ... even if you have it on DVD.
My list in no particular order (okay, so it may be military weighted ... a bit):
Patton
Battle of Britain
In Harms Way
Guns of Navarone
Star Trek: Wrath of Kahn
The Great Escape
True Grit
Alien
Aliens
Final Countdown
Ahh, hell. You throw in any WW2 war type movie and I'm usually there.
