The Hand (1981)
I love Michael Caine. He is to shouting what Maria Callas was to singing. In "The Hand" (directed by Oliver Stone for God's sake!), Michael plays a cartoonist who loses his hand in a road accident. He then develops a psychic connection with the hand and it starts killing his enemies. There are some good hand effects and a great cat-jumping-through-a-plate-glass-window scene, but it was shouting I came for and shouting I got. When the hand came off I thought I was going to faint!
