But we did watch half last night and the rest this morning. Clicking over to IMDB, I learned that John Ratzenberger voiced The Underminer. Awesome! Wonder if he did the voice work in the video game 'Rise of the Underminer', too. Survey (Google) says: yep. That's probably next on our acquisition list (or either Star Wars Lego 2). Don't forget John's great work for Pixar as Hamm.
