Jeremy Costello, Production Assistant on The Princess and the Frog, has started a blog on D23 where we can track the progress of this highly anticipated animated film. In his first posting, he reveals that 15 feet of animation footage has just been approved and another 200 to 300 feet will be produced in the coming week.
This film marks Disney's return to both hand drawn 2D animation and musicals. A lot of hopes are riding on this princess.
Here's a link to Jeremy's blog: The Princess And The Blog. Hopefully he'll share a bit about the story development in the coming weeks. I love being able to check in on a work in progress like this!
