Harry Potter actors may be too old

LONDON, May 30 (UPI) -- As the third Harry Potter film, "The Prisoner of Azkaban," premiered Sunday in London, there was speculation the actors may be getting too old for sequels.

Actors Daniel Radcliffe, Emma Watson and Rupert Grint are already working on the fourth Harry Potter film, but some believe the film's teenage stars are becoming too old to continue to play their characters for all of J.K. Rowling's seven books.

Radcliffe said that while the three actors are making the fourth film, "The Goblet of Fire," with director Mike Newell, beyond that there was uncertainty, reported the BBC.

"I think it's hard for all three of us to look anywhere beyond that," Radcliffe said. "Whatever happens in the future, I'm not sure yet."

Radcliffe said he believes his character, Harry Potter, would die in the seventh book.

"I'm going to be really unpopular for saying this," he told the BBC, "but I've always had the suspicion that Harry might die."
