I went to film school and studied Alfred Hitchcock. I knew of Alma Reville existence, but had no idea really who she was or how influential she was on him. She stayed in the shadows. Go online, and there are hardly any images or film of her. She really stayed out of the limelight on purpose. She didn't want it, and I think that's one of the reasons that she's really lost in the shadows of Hitchcock's history to a degree.

Being English definitely gave me some insight into these eccentric Brits puttering around Hollywood.

The good thing about the Anvil school of filmmaking was that it was fly by the seat of your pants. There was no safety net.

When you take on Hitchcock you know it's gonna provoke some sort of controversy, because there were so many people talking about the book [Stephen Rebello's Alfred Hitchcock and the Making of Psycho] and wanting it to be the film about the making of this movie [Psycho]. But that's been done. That's been done in the book, and Stephen Rebello himself was like, "I want a movie which is an entertainment for the audience." So we made the conscious decision.

I love the idea of creative collaboration. I love the idea of exploring marriages, particularly ones that are in process for a long time.

I think it's impossible to get any movie made, let alone a character story. Even with big stars, which we had, there were challenges. But we got through it, and we're really happy that we made the movie. It's easier to make giant robot movies, but I'm not in that game.

I think Alma Reville was the only one Alfred Hitchcock trusted. When it came to issues of taste or what the audience wanted, down to editing, script and casting, he would turn to her first. She was his partner.
