Sandra Bullock -

Sandra Bullock discussed the filming of a naked scene with Ryan Reynolds in the movie 'The Proposal,' during an episode of the 'About Last Night Podcast with Adam Ray.' "Ryan and I had these flesh-colored things attached to our private areas,' she explained. During the actual filming of the scene, they had to collide and fall to the floor. However, once the director called "cut," they couldn't move much. Ryan was on his back with his knees up, and Sandra rested on his knees, waiting patiently. She explained how uncomfortable it was, not wanting to look or move during those moments. But according to Sandra, that wasn't even the most uncomfortable aspect of the whole experience.
