This scene is one of Kurt Russell’s finest hours and Tombstone is one of the all-time great Westerns. The Kevin Costner film Wyatt Earp may be more historically accurate (maybe) but this is far more entertaining as a movie.
Here we think that the Earp family are running away from the outlaws in the town instead they have different plans.
Wyatt (Kurt Russell) shoots Stillwell on the railway platform and gives Ike Clanton a message to deliver to the rest of his gang.
Interesting tidbit from IMDB: apparently in this scene Wyatt is standing in front of train car #5150 which is the California police code for a crazy person. #themoreyouknow
