Paul Rudd finds male nudity in movies hilarious - except when it's his bare bottom on show.
He explained, "I'm a big fan of movie nudity. A male ass shot is the cheapest and best laugh ever. But it's mortifying to do. When I showed my butt in The 40-Year-Old Virgin, all I could think was, 'This is going to be up on all those big screens.' I was very self-conscious about doing it."
Rudd most recently starred in "Our Idiot Brother" about scruffy idealist Ned who wreaks havoc on the lives of his mother and three sisters, Miranda (Elizabeth Banks), Natalie (Zooey Deschanel), and Liz (Emily Mortimer), while overstaying his welcome in each of their homes and voicing his opinions when they aren't wanted.
