I'm not much of an actor myself, but as a frequent theatregoer, I wholeheartedly support this as the most liberating thing an actor can do. I have seen many productions where nudity has enhanced the show.
When Naked Boys Singing played in Minneapolis, the production was actually better than the one I saw in Chicago, but there was less nudity. It's a shame, because in moments such as The Entertainer, which was performed in sheer underwear, the nudity would have improved the sequence. Blue Blake was better in the Minneapolis tour of Making Porn than Rex Chandler was in New York, too.
