"They knew what I did on my hiatus so as soon as I showed up back on set, they were all pointing and doing the body rolling," Manganiello, 35, tells me. "There was a week on set where Steven, Anna and Alex and I were working together and we were humping chairs, humping the trashcans. We were humping everything in sight on set. It become a huge joke to the point that I was skipping onto the set and saying, 'Did somebody order a werewolf?'"

We could only imagine what they'll do once they see the scene in which Manganiello is shown, um, fluffing himself with a plastic penis pump.

"It's like a medieval torture device," he said. "I tell everyone that we were such a low-budget film we couldn't afford fluffers so they were like, 'Here ya go.'"
