The actor, who shocked fans when he appeared naked on Broadway in Equus in 2008, has stripped down in three movies this year – and shared a bathtub with Jon Hamm on TV – but he told Ellen DeGeneres on Friday that his nude streak was "not intentional."
"I'm comfortable with it, but I do like to point out, I don't request it," he jokes.
"You do take your clothes off a lot," DeGeneres teased. "In a lot of things."
"They're jobs," Radcliffe, 24, clarified, adding that he doesn't strip off in public "in stores [and] places I go."
Radcliffe, who plays beat poet Allen Ginsberg in the new film Kill Your Darlings, admitted he had a conversation with an actress friend who has also done a lot of nude scenes and told her that he worried they were "going to start getting called exhibitionists."
