There's a great featurette of TMNT online just now. Patrick Stewart, Sarah Michelle Gellar, Laurence Fishburne and Kevin Munroe talk a fair bit about the film and it's all accompanied with loads of footage.

Surprisingly the footage here is much better than some of the stuff I've seen online to date, even in the trailer. Some of these action sequences look stunningly good and I wonder why we haven't seen them in any of the trailers to date.

You can see the International Featurette over at Apple Trailers [QT:L].
