The documentary filmmaker, who won an Oscar in 2004 for The Fog of War, recounts how he was inspired by Alfred Hitchcock's 1960 thriller Psycho.

'I spent a fair amount of time just interviewing murderers. I became obsessed with killers,' says Morris, who moved to Plainfield, Wisconsin to be close to Gein. 'It's this lonely farmhouse out in the middle of nowhere where Ed Gein lived. Cannibal, ghoul, human taxidermist and a couple of other things I don't need to go into.'
