Watch Hugh Jackman 'break' a professional wrestler's jaw

If you need to promote a movie about boxing robots, what better place than the world of robotic actors - professional wrestling?

Actor Hugh Jackman, who portrays a former boxer-turned-manager in the upcoming "Real Steel," was a guest on WWE "Raw" this week. It didn't take long for the man who also plays Wolverine to stick his claws, er, fist where it did not belong.

The following day, the wrestler punched by Jackman, Dolph Ziggler, tweeted that he had suffered a hairline mandibular fracture - certainly not part of the script, if true.

And give credit to Jackman - he looks like he is having a blast.
