Fantastic interview!! I didn't know Tom was originally asked to audition for Thor, I can't imagine him as Thor, Loki was the perfect character for him to be cast I think, they got it spot on. Kudos to Ken for that I guess!
On a side note, I watched War Horse the other day, brilliant film, fully recomend it! Only tbh I thought his role was bigger, he's only actually in it for probably less than 10 minutes screen time. Stll fantastic though!
