Hang 'Em High is a 1968 Clint Eastwood Western. I do dearly love Clint Eastwood Westerns, and this is a fine example. Also in this film are Inger Stevens, Ed Begley, Pat Hingle, Alan Hale Jr. (Gilligan's Island, It Happened on Fifth Avenue), Dennis Hopper, Mark Lenard (who has a Star Trek connection), Ben Johnson, Bruce Dern (Silent Running), James MacArthur (Hawaii 5-0) and Ruth White (The Nun's Story). I always enjoy this movie.
Roger Ebert gives it 3 stars and a rambling review. Rotten Tomatoes gives it a score of 92%.
