The clergy is in the same business as actors, just a different department.

With [Fred] Zinnemann I did A Man For All Seasons. He was my screen godfather. I'm happy to say he was.

I certainly don't see myself as Caligula.

By the very nature of being a clergyman's son, people tend to put you slightly apart, which is - you tend to live a life, at some stages, as being - people being suspicious of you and puts you rather on a - I don't mean lonely, particularly. But it does tend to put you apart.

The director [Elfar Adalsteins] came to me through my agent and I had a read of the script [of the "Sailcloth]. I thought immediately this is someone who is writing for the cinema. Not having to go through the tedious business of taking something from literature and making that awful leap that is so difficult to make anyway, from literature to cinema. It's refreshing to be able to deal with a subject like that, to be written where the driving force is the image on screen and you don't need any words. The more that we can do that [in film], the better.

I mark a script like an exam, and I try not to do anything under 50 per cent. Similarly with the part. And also film is a peculiar thing, parts don't necessarily read in script form anything like as well as they can do when it comes to materialising.

If I hadn't been a part of [Harry Potter] I would have been deeply upset.
