Graham Moore from "The Imitation Game," about British World War Two Nazi code breaker Alan Turing, won best adapted screenplay and dedicated his award to the late Turing, who died in 1954 a broken man, persecuted for his homosexuality.
"He was probably the greatest genius of his generation and I am a screenwriter from Chicago. So it's very strange to be standing on stage now when he should be," Moore said.
