Park and Box are both smart, soft-spoken chaps and the result is a nice, smooth commentary with plenty of interersting tidbits about the world of "Wallace and Gromit" and the process of developing and making the feature.

They talk a lot about the music in the movie, how it was like to work with Hans Zimmer, and the challenges of creating a score that is successfuly combining the "smallness" and the "bigness".

We get to learn about the many sequences and short scenes that, for whatever reason, didn't make the final cut or were simply not shot. Yes, there is some dead air, but it's certainly not something that would make you hate the commentary.

Park and Box also talk about the comedy in the movie and the many differences between the short "Wallace and Gromit" films and this one ("This one is bigger. You meet these crazy, upper-class characters and the whole thing suddenly branches out", says Park). The on-screen combo of clay and CG-characters is also addressed, along with the design of the new characters.

Park reveals what was the hardest part of writing the picture (it involves a certain character's transformation) and both of them talk about the inspirations behind some of the "horror" elements in the movie.

Personally, I liked the commentary. Recommended mainly for fans of the "Wallace and Gromit" universe. You will be pleased.
