Wyatt Earp Remake

How would you cast a new version of the Wyatt Earp saga?

I watch "The Life and Times of Wyatt Earp every day, On Demand. I was too young to understand the Stories originally broadcast in the late 1950's, but I've been watching regularly for many months. I've seen most of the other Wyatt Earp films produced and directed by the high stepping Western sort of producers and directors. I like Kurt Russell. I really like Val Kilmer.

This is, if I could cast Wyatt Earp:

Leonardo DiCaprio - Old Man Clanton

Matthew Mc Con
