I work best when a little scared, when there's so much more than the lines to think about.

When I told people I was going to be doing the movie and the voice of Dobby, they were kind of awestruck, the people who knew about Harry Potter. I felt rather guilty that I didn't really understand the scale of the job I was about to take on. Now, I am well aware of what I'm doing, and actually, it feels a very serious acting responsibility.

Somewhere the glamour has gone because of the industrialization of this whole process. I wish it [filming] felt as magical and glamorous as people want it to be, but it feels like a routine people are going through.

I still don't feel I know Hitchcock at all. I find that the more one looks, the more elusive he becomes. But my admiration for Hitchcock the filmmaker remains undiminished. He is a giant of the cinema and the darkness in him informs his cinematic language. You can't separate one from the other.

We're interested by public personas and private personas, otherwise we wouldn't put on with actors rambling on with the same kind of stuff, over and over again, saying variations of the same thing. I'm always amazed by how fascinated people still are by actors because it's the same version of events that actors describe, all the time.

I think it will be, as always, interesting to compare different portrayals of Hitchcock. I'm very honored that I'm playing the same part as Anthony Hopkins.

The thing about Hitchcock which is quite extraordinary for a director of that time, he had a very strong sense of his own image and publicizing himself. Just a very strong sense of himself as the character of Hitchcock.
