When Piranha 3D finally hits theaters, rabid fish won’t be the only things capturing our attention.

During an interview with Jimmy Kimmel, Jerry O’Connell – who plays a “soft core pornography mogul” in the film – made a big reveal. “I show frontal,” the married father of two teased.

Should this spoiler lure you into watching the film, O’Connell would like you to know something beforehand. “There may be some issues with the piranha…and my member…maybe,” he warned. Why? Because a “very cold” Colorado River was rushing into the body of water (Lake Havasu) they were filming in.

“So when you see me, it’s very cold water,” he insisted.

If you’d like to gauge that water temp for yourself, the film opens this weekend.
