From what I understand, they really want to make this new Pooh film have the same look and feel as the original Pooh films, and they will be using a lot of material from the original A.A Milne stories that has not yet been tapped into.Uh... I really don't know how a sequel's gonna go... I mean, I've thoroughly enjoyed the Boom Comics Monsters Inc series, which works better than any sequel would in my eyes. And I really don't see how much more could happen in film form. Monsters Inc is one of my top three Pixar films... along with Up and the Incredibles. And I hear they were considering an Incredibles sequel... and I'd rather see what they're gonna do with that one.
Hmm... new Pooh, huh? I wonder if they're planning one closer to the original story, and I wonder if we're gonna have new character designs
At John Lasseter's keynote address for Disney and Pixar Animation at the D23 Expo, he stressed that this new Pooh film will not just be for kids, that older people will be able to enjoy it as well.
So it seems that they really want this new film to have a classic feel.
As for the Monsters Inc sequel, John Lasseter will no doubt be executive producer, and I have faith in all of the projects that he is associated with. So I am not too worried about that. Since Lasseter is involved, I'm sure that the story will be well thought-out.
As a side note, Cars 2 is coming out in the summer of 2011, And last I heard the film was apparently having some story problems, so Lasseter went up to Pixar to help the team work things out.
(I really enjoyed Cars, so I'm looking forward to the sequel.)
