From an interview at bodybuilding.com:
[ Q ] One of your co-stars Vinne Jones used to be quite a violent pro soccer player prior to his acting career. Did he want to exchange a few moves with you?
[ A ] Vinne Jones is actually one of the nicest dudes I met in a long time, all we did is have great laughs and have a good time. He didn't want to know anything about fighting. I didn't even know that he was a violent soccer player, you couldn't tell by hanging out with the guy. He is the nicest guy. Maybe not so much when you pissed him off. Like you pissing me off asking me these questions about knocking out Chuck with a lucky punch.
