Jerry O'Connell Talks Full-Frontal Nudity in 'Piranha 3D' (VIDEO)

Usually, if a Hollywood actor is going to show his bits on film, the context better be deep and meaningful. But a Piranha horror film? In 3D?? That would be the decision of Jerry O'Connell in 'Piranha 3D.'

"I show my [he whistles] because I play a softcore pornography mogul who videotapes girls at Spring Break," said O'Connell on 'Jimmy Kimmel Live' (weeknights, 12:05AM ET on ABC). "I don't want to give too much away, but it is in 3D, and ... there may be some issues with the piranha and my member. Maybe."

O'Connell hastily added a disclaimer. "The Colorado River -- very cold river -- rushes into Lake Havasu," the Arizona lake where the movie was filmed. "So when you see me -- it's very cold water," he explained. Noted.
