I've debated on whether or not to post this (there have been SO many PatF posts recently!) but figure some might be keen to see it.
It's the first five minutes (the opening, without the titles) from Disney's The Princess and the Frog. It isn't all completed animation, which is kind of nice to see actually, but it is continuous, except for the last 30 seconds or so. I think this is now available because it's on the Snow White Blu-ray disc as an 'exclusive preview' which was released on Tuesday.This clip is, unfortunately, heavy on the little-girl-princess aspect and doesn't show how the movie is likely to appeal to more than little girls but it does have an amusing scene with a frog with Tiana as a little girl.
Here's the last 30 seconds or so which seems to be missing from half the review sites - it's the part I like best. Enjoy!
