If you have watched my early post of interview with Jamie Campbell Bower with MTV you will hear it from his own words, but if not!!! this is what he said!!!
“We just all sit there, completely naked, for one scene. Yeah, it’s me, Michael Sheen and Christopher [Heyerdahl]; we just sit there, naked.” Bower said. “”It’s a full-body shot, and then Peter comes in, and it all gets a bit awkward,”
or you can watch the video again here
