The Outlaw Josey Wales is my favourite. There is so many lines out of it that are just brilliant. Unforgiven & How Green Was My Valley is up there too. TBH though I'd watch anything with Clint in it. I thought Once Upon A Time In The West was a little overrated given it's status, even though I'm a fan of Henry Fonda. I'll hold my hands up & say I haven't seen The Good, The Bad, & The Ugly I'll get around too it soon though.
