The 36-year-old actor rang his agent in a rage when he realised he was not the only choice for the role, and his fragile ego almost got the better of him.
He says, "I remember going to the audition and somebody else came along and the producers saw him before me.
"I rang my manager and said: 'What's going on here? I'm leaving!'
"Thank God I didn't, because otherwise I wouldn't be here now."
