Lots of good ones here, I'll see if I can rattle off a few:
The Eiger Sanction- Clint Eastwood
Eldorado- John Wayne
They Live- Rowdy Roddy Piper
The Bedford Incident- Richard Widmark, Sydney Poitier, and Wally Cox
Slingblade
I can't think of the name of the one that had Eastwood, Garner, Donald Sutherland, and Tommy Lee Jones in it, but it was great!
In Harms Way
Midway
Tora Tora Tora
Pearl Harbor- I don't care about the love story in it, the facts were accurate, and the effects were awsome!
Heavens Gate-the uncut version
