Telly Savalas.
Maggot in The Dirty Dozen.
Maggot was a racist, psychopathic serial killer who enjoyed raping and murdering women. Savalas plays him as pasty and soft and whining and giggling and completely vicious. He was probably the worst soldier in the U.S. Army, totally incapable of thinking of anyone except himself and Savalas really let’s you see that.
vs Big Joe in Kelly's Heroes
The platoon sergeant of a reconnaissance platoon, Big Joe is a complete pro, tough, tactically competent, cool under fire and an excellent leader who takes real care of his people on and off the battlefield. Savalas really shows you Big Joe’s strength and is totally believable in the role. One of my favorite fictional soldiers, actually.
Watch the movies back to back sometime, the contrast between the two characters is remarkable.
