Who Should be Nick Redfern?

If you read the post below then you know they are making a film of Nick Redfern's Three Men Seeking Monsters. Who will play Nick? I've been thinking on it and the best I could come up with was that Paul Bettany should shave his head and take on the role of Nick Redfern, mostly because he is a great actor and also because he is English. What actor do you think could do a good job as Nick Redfern?
