Unless he is being discussed elsewhere, I'm surprised that he hasn't got a thread all to himself. He has now.
He first graced my telly screen in The Beyond. He had a cool vibe about him and I always liked the ireverrant way he pushed bullets into the barrel of his gun in the hospital lift. His commentary on the DVD is class.
Particular highlights of his career for me are his appearances in the Gui La Testa and The Last Hunter.
Gui La Testa is of course Duck You Sucker, or more commonly known as A Fistful of Dynamite. If you've seen the remastered uncut version, Warbeck's character is incredibly poignant and important.
He was taken from us far too early.
