Brian Henson does an okay job of talking about the movie and some of the techniques he and the crew used to make it. He talks about forced perspective used in the movie, to the sets being high off the ground to support the puppeteers, and he also talks briefly about the origins of the movie.

Sadly, by the end of the review it does not feel like he has said very much and there are a lot of dead spots in the commentary. I would say give it a listen if you're interested in learning to techniques for doing a movie with puppets or are a big Muppet fan but otherwise you can probably skip this one or maybe get one viewing out of it.
