When someone sees Coburn face just after he takes off the helmet at the beginning of Giù la testa (a.k.a. Duck you sucker - and another 3 or 4 titols...), with Morricone's "qua qua music" - as I call it - well, he never forgets it for the rest of his life. This is my opinion.
As well as Fistful of Dynamite,I also thought he was great in pat Garrett and Billy the Kid .
