I studied Hitchcock a little bit at University and knew the famous story about the Birds - that he'd tortured Tippi for a day using real birds. I had no idea that it was a five-day onslaught and that it was the tip of an iceberg that carried on through to another film.
I'm not a great science fiction fan myself. I probably feel that way about Westerns. Like I used to play Cowboys and Indians they can act out Will and the Robot.
