In a new interview on the set of Harry Potter and the Deathly Hallows, actors Daniel Radcliffe and Rupert Grint weighed in on Goblet of Fire costar Robert Pattinson's rise to great fame via the Twilight series, and how they deal with it as part of a major franchise.

Speaking about fame, Radcliffe said: "It is totally mad, when people are screaming and going absolutely insane for you.

"Particularly with Robert - the amount of women that would jump on him - you have to keep it in some kind of perspective, by thinking 'well, partly they like me and partly they are just attracted to the character'.

"As long as you don't think 'oh yeah, God they're all doing this - I must be absolutely fantastic'. As long as you do that, you should be all right."

Rupert praises Rob for having done amazingly with coping with the media attention, and how he deals with it himself.

"It's never been normal. I'm slowly getting used to it, but it's quite strange," he told the BBC at a launch event for the Harry Potter and the Half-Blood Prince DVD, out in December.
