The actor, 44, who once grooved as rap sensation Marky Mark, even hired a choreographer friend to help him perfect his moves, reported Contactmusic.
"I dreaded the dancing stuff. "(Director) Sean (Anders) continued to ask me, 'You workin' on your moves?' 'Yeah,' I said, and I wasn't.
"I said, 'I might need a choreographer', so I could get my friend Ace a cheque, and he'd come to the trailer and say, 'Hey, let's work on the moves'. I was like, 'Will you leave me alone? I'm not working on the moves!' It's my least favourite thing to do next to singing, and of course I had to do both in the movie. But people seem to love those moments.
