Who do YOU think should have played the Three main characters?

I'm quite happy with the casting for Michael and Mina, but dearly though I love Tim Roth, I would have chosen Paul Bettany for Skellig 'cause he looks more frail and rugged and he's a brilliant actor.

I thought the kids were terrific. I could see John Hurt as Skellig, however. Tim Roth never seemed as old or as feeble a character as I recall from reading the book.
