The Hands Of Orlac
THE HANDS OF ORLAC is an Austrian silent horror mystery, from 1924, in which a concert pianist's hands are transplanted with those of a murderer.
There are regular scenes of mild threat and horror in which a pianist seems to be possessed, and driven to insanity and violence, by his transplanted hands. A criminal persuades a reluctant maid to 'seduce' the pianist's transplanted hands, and she is seen motioning as if to kiss them.
A man stabs another, but without sight of infliction. Corpses are discovered, each with a knife embedded bloodlessly in their chests.
There are scenes of emotional upset. A man's mental health is thrown into doubt. There is use of very mild bad language ('damn', 'God').
