Daniel Radcliffe Says He Probably Won't Appear In 'Harry Potter' Spinoff

People are still asking Daniel Radcliffe to comment on J.K. Rowling's upcoming "Harry Potter" film spinoff, "Fantastic Beasts and Where To Find Them," and Radcliffe keeps saying the same thing about his potential involvement: never say never, but it's doubtful.

"I would obviously never close the door on something like that entirely, because it would be foolish to. But I don't know under what circumstances I could be convinced that it would be a good idea to do it again," Radcliffe said during an interview with a local CBS talk show in New York. "I'm going to be 25 this year, and Harry's a character that sort of ended at the age of 17. I'm getting a little long in the tooth to be wearing a schoolboy's outfit."

Rowling will adapt "Fantastic Beasts and Where To Find Them," a Hogwarts textbook she wrote in conjunction with the "Harry Potter" series of novels, into a film trilogy for Warner Bros.

"Although it will be set in the worldwide community of witches and wizards where I was so happy for 17 years, 'Fantastic Beasts and Where to Find Them' is neither a prequel nor a sequel to the 'Harry Potter' series, but an extension of the wizarding world," Rowling said about the project in a statement last year.

As such, the movies will focus on Newt Scamander and take place 70 years before Harry Potter's birth, meaning even if Radcliffe was hoping to star, some narrative tomfoolery would be required. Not that Radcliffe hasn't thought of that either: As the actor joked when he first heard about "Fantastic Beasts" last year, Potter could appear in the films "if time travel rears its head again."
