Theater increases security to protect nude Daniel Radcliffe

Previews of the show -- which sees the 19-year-old Harry Potter star strip completely nude -- kicked off on Friday, September 5.

Theater designer John Napier explains, "If you put Harry Potter on the stage with people directly in front of him, you're likely to get a lot of screaming young girls, particularly when he takes his kit off. It was a very sensible decision for us to raise the audience up. There's more of a barrier."

Radcliffe recently said that starring in Equus "has given me a little more confidence" – and his nude scene is no big deal.

"It's only seven minutes at the end of the play," Radcliffe told the audience at an Aug. 19 talk held by the New York Times.
