Rupert Grint going Naked

Is it just Harry Potter (Daniel Radcliffe)going naked? I doubt so. Now Ron Weasley (Rupert Grint) is going naked as well.

Previously as most of us know that Daniel Radcliffe has taken up a new role in the broadway, which needed him to go all naked and have sex with a horse (if I didn't get the information wrongly). Many said he was stupid for taking up such a role, just to get more popular than he already was. Well, that was from what I've heard.

And now, one of Harry Potter cast is going naked as well. Rupert Grint will be going naked in another film he has taken up on. And there's a sex scene as well with co-star Kimberly Nixon.

I won't go further down about the details because I do not know of it well. Who will be next? Emma Watson?
