Tombstone is awesome, I don't watch it much anymore because I've seen it so many times. Biehn plays an great villain and the cast is incredible.
This film has Bill Paxton, Michael Biehn, Michael Rooker, Kurt Russell, Val Kilmer, Sam Elliot, Charlton Heston, Stephen Lang, Billy Bob Thornton, Billy Zane, Thomas Haden Church, and Powers Boothe.
If you have any interest in Westerns I recommend checking it out.
Also I think Biehns villain in The Abyss is one of the best things about that film.
