I grew up on Clint Eastwood movies.
His westerns are unparalleled in my opinion.
Top Five in order:
The Good, The Bad, and The Ugly
High Planes Drifter
A Fistful of Dollars
Two Mules for Sister Sara
Unforgiven
Unforgiven makes the list only because he makes that crazy "I'm going to kill you" psycho face almost the entire movie.
But, Pale Rider, Hang 'Em High, and For A Few Dollars More are also excellent films. The only movie I refuse to watch is Paint Your Wagon. I rented it once and it opened with a musical number and i took the disk out and brought it back to the store that night. I didn't even want it in my house.
