Pam Marsden hosts this commentary and introduces each speaker, who tells you about their job on the movie. This commentary is a bunch of crew members, so it's very technical. Everyone is recorded seperately, so you don't get interaction and wacky anecdotes, but as technical commentaries go, it's as solid as they come. We hear about most every aspect of production: character design, shader programming, the perils of combining CG characters and live action backgrounds, lighting, shooting locations, comparisons to real dinosaurs and more. Some of the people are more interesting than others, but everyone gives plenty of information and there are virtually no dead spots. Recommended to anyone interested in the technical/design side of CG or effects animation.
