Quite a few readers of the blog sent me emails about the Redux Riding Hood project.
Celbi Pegoraro sent me the URL of an article he wrote (in Portuguese) a while back on Animagic about that same subject and that clarifies, among other things that:
Jack and the Beanstalk was directed by Peter Tolan ("Larry Sanders") and seem to have stopped in post-production and that Three Little Pigs with a script by Frank Coniff seems to have been completed but never released, not even in festivals.
Jenny Lerew posted a comment that mentioned:
I freelanced some storyboarding on Three Little Pigs for Darrell Rooney (I was working at Turner feature animation development at the time, where I'd met Darrell). I believe Ricky Nierva, now at Pixar, and Scott Morse (also up there at Pixar) did freelance boards too (Ricky, who is a brillaint young designer, might have done the character designs as well--I'm not sure--can't remember).
I never saw the finished product, either, though--why Disney never released them is a mystery to me, but they were having a kind of rollercoaster of management at that time, and perhaps a new exec in charge couldn't see a venue for them. They were at one point supposed to be released on a home video(now it'd be a DVD, of course). I'd be surprised if they stayed unseen forever.
I can't remember what the "4th" film was...hmmm...it's about 10 years ago now."
