RUPERT Grint won't be following his Harry Potter co-star Daniel Radcliffe and treading the boards any time soon.

"The stage is a very different experience, you only get one chance to get it right," says the screen's Ron Weasley.

Daniel Radcliffe famously stripped off in the London stage revival of Equus in between filming the Harry Potter movies. Grint is tempted to do theatre but doesn't seeing it happening yet.

"When I think back to my school plays, I did get quite a good buzz out of that. So maybe it would be good, but I can't really see it yet because I don't think I've got the guts to do it yet. I'm quite comfortable with the films. Maybe it's something I'll do in the future, we'll have to wait and see."

He has something to look forward to in the next Potter movie - a screen kiss, although it's unlikely to cause as much comment as Harry's first snog in the latest film, Order Of The Phoenix.

There's an open casting call for a girl to play Lavender Brown who kisses Ron in the next film. "I'm not really looking forward to that, because in a film I did called Driving Lessons, I had a screen kiss and you had the whole crew watching so that was a bit embarrassing. But it'll be interesting."

He and the rest of the regular cast won't have to worry about working with a new director as Order Of The Phoenix's David Yates has signed to helm the next one. Chris Columbus directed the first two, which Grint found helpful as a newcomer to movie making.

"We got to know him really well, and he was cool," he says. "It was quite scary having Alfonso Cuaron come in, change things around a bit in the third, but he was really nice too. And ever since then it's been quite exciting having a new person each time. They've always been a little bit different and added their own things.

"Mike Newell, director of Harry Potter And The Goblet Of Fire, was a lot more shouty and wasn't afraid of swearing at you if you got it wrong. On this one, it's David Yates, who's really laid back and very calm.

"It must have been quite scary for David because it's quite a bit thing to take on, and it's been the same cast for eight years.. "

It was back in 2000 when Grint, Radcliffe and Emma Watson were revealed as Harry Potter's young stars. Aged 11 at the time, Grint remembers it was a crazy time. "But I look back on it with some good memories because it was really fun too," he says.

"I had very little expectation of how big these films were going to be, though. I was more worried about the filming process because I had very little experience. The only thing I'd done before was play a fish in Noah's Ark. That was quite scary.

"I remember the first premiere, that's when we realised how big it was going to be. We knew it was going to be quite big because the books were already huge, but each time it's been amazing."

He hasn't thought about what he's going to do once the Potter series is over. The sixth one begins filming later this year. "I guess I want to continue doing this. We'll have to wait and see what comes up," he says.

He's starred with Julie Walters, who plays his mother in the Potter films, in the more adult drama Driving Lessons but finds it hard fitting in projects between the Potter films because they take up most of the year. "So usually, when we get a break, it's nice not to do anything really because it tires you out a bit," he adds.

In Order Of The Phoenix, he sees Ron as a lot more serious and tougher. "It's quite a dark time because of Voldemort's return, and they've got some really evil people in this one. It's quite a frightening time for him and he grows up quite a bit," says Grint.

His only disappointment is that Ron's Quidditch scenes were cut from this film. He was looking forward to them but understands that, being such a big book, some things had to be omitted. "When you watch the film, you don't really miss it because of the main storyline with Harry. It's quite intense. But next year I've got some Quiddich, so hopefully they'll keep that in," he says.
