Daniel Radcliffe was intimidated when he met James McAvoy.
Radcliffe was never fazed when working on the 'Harry Potter' films alongside acting greats such as Alan Rickman and Gary Oldman, but was "in awe" of his 'Victor Frankenstein' co-star because he has always been such a fan of his work.
He said: "I was much more in awe of James than I was initially with a lot of the senior actors on 'Potter'.
"When I first met Maggie Smith, I Was nine and did not know who Maggie Smith was! I had not seen 'The Prime of Miss Jean Brodie'. I was gloriously unintimidated by all of those people.
"But when I met James, I'd grown up watching 'The Last King of Scotland.' 'Inside I'm Dancing' was a huge f***ing film to me and I remember being obsessed with 'Atonement'.
"Suddenly you're working with him. That was very intimidating."
Luckily, the two actors got on very well and Radcliffe thinks his new friend gave a "phenomenal" performance in their movie.
He told Total Film magazine: "What he brings to the character is phenomenal. He's f***ing extraordinary in it."
