The RED DRAGON star, who had criticised the past two installments in the hugely popular series, is extremely excited about his role in HARRY POTTER AND THE GOBLET OF FIRE - and he admits that simple drawings persuaded him to accept the job.
He says, "I wrestled with it a bit because I didn't know the world of Harry Potter. Then after thinking about it I just thought it was a full-on, meaty villain, baddy.
"I've done realistic villains but something in that fantastical realm, children's realm, the dark Lord; I hadn't really done that before.
"When I saw some pictures that they drew for the look (of the character) that's when I took the bait. I thought it looked really cool. I think I'm doing the next one where I have a big fight with DUMBLEDORE."
