Here is a quick watercolor study I did from a still of The Birds. This is the scene where Tippi Hedren is attacked by birds in the upstairs bedroom. Hitchcock told her that mechanical birds would be used. Instead, ravens, crows, and gulls were flung at her for five days. Rubber bands were used to clamp their beaks shut. When Cary Grant visited the set, he told her, "I think you're the bravest lady I've ever met." After the shoot, she had nightmares of flapping wings.
Man:What are you doing for work today honey?
Tippi: I'm going to go to a studio set and have live birds flung at me while a fat man watches.
Man: Awesome.
