Taylor Lautner had mixed feelings about a fight scene he filmed. On 'Late Show' (Weeknights, 11:35PM ET on CBS) he went into excruciating detail about the filming of one particular uppercut. It was Lautner vs. a 6'5" Russian actor, so there was a definite size disparity.

When the scene wasn't playing believably enough, the stunt coordinator suggested Lautner extend more and the other actor stick his chin out more. That's a recipe for a great and believable shot.

And it certainly was believable, because it was absolutely real. Lautner completely knocked the other actor out, and even did some damage to the guy's mouth. In other words, it was a great take!
