The Not So Many Faces of Jack Black

It’s hard to tell one premiere from the others in this time-lapse photo gallery of Kung Fu Panda voice Jack Black.

In addition to recycling his favorite t-shirt, Jack sticks to one tried-and-true wacky face to amuse the various press lines.

The portly comedian must have burned loads of calories at each successive premiere, landing kicks and striking kung fu poses.

But if there are any “before and after” pictures here, you won’t know by looking at his mug.
