Rupert Grint admits that it was “nerve-wracking” filming his first sex scene.

The actor had already had an on-screen kiss in Harry Potter and the Half Blood Prince but says getting intimate in new movie Cherrybomb was a lot harder.

“In Harry Potter it was just a kiss, really. It was suggestive more than anything. This was a lot more intimate. It was quite nerve-wracking. I was quite nervous about it.”

Although he got his top off for the scenes, Rupert doesn’t think he could follow in his Harry Potter co-star Daniel Radcliffe‘s footsteps and strip off completely: “I don’t think I could. Just being on stage would be quite a scary thing, let alone with no clothes on. It takes a lot of courage.”
