Trivia, insights & behind the scenes
Link was played by Locke the orangutan, who also appeared in Clint Eastwood's Every Which Way films. Locke reportedly threw actual tantrums when not filmed first.
Richard Franklin, a Hitchcock protégé, specifically wanted to create 'the Psycho of animal horror'—notice the shower scene homage when Jane discovers the chimp's body.
