The Belfast-based flick casts Grint as a troubled teen experimenting with a wild weekend of drugs, shoplifting and stealing cars. And while he confesses the embarrassment he went through during the filming of his first ever sex scene, he says the worse was watching it with his mum and dad.
Grint reveals movie bosses handed him a preview DVD of Cherrybomb, which dad Nigel and mum Joanne were quite eager to watch.However, neither of them knew what lay in store for them. "Filming it was a really nerve-wracking experience but the worst bit was watching it with my parents," the Mirror quoted Grint, as saying.
He went on: "It was agonising. The scene's quite tastefully done but it's not the sort of moment you really want to share with your mum and dad. When the scene arrived we all sat there not really saying anything. Afterwards nobody talked about it, which was kind of a relief." Grint also opened up about the filming of the sex scene, saying: "Shooting the sex scene was a pretty anxious time because I didn't know how it would be shot. It's the anticipation that scares you most."
Taking about his co-star Kimberley Nixon, he added: "Obviously, I really didn't want my bum up there on the screen but the scene isn't too graphic and most of it is suggested rather than seen. But you do feel very self-conscious. It was more embarrassing for Kimberley because a lot more of her body is shown. But you just have to get into that moment and get on with it."
Grint now feels he would be better at a racy sex scene, if it is offered to him again. He said: "Now that I've done one, next time I'll be totally fearless...Or at least less nervous."
