Please let me know if any of these should be replaced with other, more worthy candidates, or if you feel that there are some that don't qualify as westerns. I think we're going to allow comedies, since there are some really good westerns that could be considered comedies.

Finally, since no one mentioned these yet how about the following three:

Geronimo (with Jason Patric and Matt Damon)
Wyatt Earp (with Kevin Costner)
The Beguiled (Eastwood in one of his most different roles of his career)
