Top 5 gun showdowns in movies

1. Once Upon a Time In The West - Harmonica vs. Frank, in the grand finale.

2. Enemy At The Gates - Vasily Zeitsev vs. Major König, multiple engagements.

3. The Killer - Ah Jong and Li Yeng vs. the Triads, their last stand in an abandoned church, a John Woo classic.

4. Way Of The Gun - Parker and Longbaugh vs. the "old man army," eyes on the prize in the courtyard of a Mexican brothel.

5. The Magnificent Seven - The seven "ronin" vs. Calvera's bandits; Charles Bronson makes a second appearance on the list!

I'll lay off the commentary so as to avoid spoilers. You've really got to see these movies to appreciate the scenes themselves.
