My favorites...
No. 1 would be Wayne's "Stagecoach", then, in no order; El Dorado, Liberty Valance, Sons of Katie Elder. True Grit and Rooster Cogburn (I'd like to see 3 people load a Gatling on a bobbing ferry boat for real)!!! Any John Wayne western. Any Kirk Douglas western. Evil Roy Slade!!!
The "Sackett's" and any Selleck and/or Elliot movie. Both "Support your Local" movies.
Any Clint movie; but High Plains Drifter, The Unforgiven, and "Josey Wales" tied for Clint fave.
Lonesome Dove. Butch Cassidy. The Wild Bunch. Jeremiah Johnson. Cat Ballou.
2 movies I love but can't find: McCabe and Mrs. Miller (Warren Beatty and Juliet Mills???) and
Great Scout and Cathouse Thursday (Lee Marvin and Oliver Reed gut bustingly funny)!!!
Two ain't westerns that are better than a lot of "real" westerns: "Last Man Standing", and
"Bad Day at Black Rock". "Bad Day" is one of the best movies I've ever seen.
There's a bunch more I ain't got room for. Funny, I'm not even into cowboy shooting; I'm just
a biker who likes to shoot black powder almost as much as I like my BSA.
