Harry Potter and the Goblet of Fire: In a recent interview with Sci-Fi Wire, actor Robbie Coltrane, who plays 'Hagrid' in the Harry Potter films, talked about his commitment to the 3rd film and 4th films, but unsure about going further then that...

"I'll certainly do four," Coltrane said in an interview during a break in filming last fall on the set in England. "I'm contracted through four. ... Beyond that, I don't know. Never say never again, as they say."

In the third film, Harry Potter and the Prisoner of Azkaban, Coltrane's character finds himself teaching a class at Hogwarts. "Yes, he's a professor, which is quite funny," Coltrane said. "We had a lot of fun with that, because the kids are kind of enjoying the fact that Hagrid doesn't quite know what he's doing because he hasn't done it before. So there's a lot of things like, 'How am I doing?' And 'You'd better do better.' He's not really quite sure what to do."

Coltrane added that he has had conversations with Potter author J.K. Rowling about Hagrid. "I know all sorts of things about his past that haven't been discussed so far, which will be important," Coltrane said. "I mean, that's all Jo told me. I said, 'Well you can tell me everything about his past, which is important, even if it's not expressed to everyone but me. Even if it's irrelevant to everyone but me, because I think it is relevant if you're going to be a character.' So that's all I know. I know stuff about his past that isn't revealed. But I don't know anything of the plot. I don't want to, either. You know what I mean? I want the fun of finding out as much as anyone." Azkaban, which is now in post-production, is slated for release June 4.
