Wow...lots to comment on here!
"Kenny Loggins, composer of The Tigger Movie" - Actually, that would be the Sherman Brothers, their first Disney assignment in many years and their most recent so far. Loggins merely collaborated, and sang, the film's end credit song.
"...another Tigger film. Has anyone heard anything else on it?" - Ahh, it doesn't say he's working on an actual Tigger <I>movie</I>...just that he's working on a new <I>album</I> that will be tied to its release.
The only Tigger/Pooh movie in production right now is "My Friends Tigger And Pooh And A Musical Too", a feature-length capper to the TV show, to be released to DVD next spring. This <I>may</I> be the project to which Loggins is referring too and, if so, then you'll be disappointed to know that it's CGI animated.
It's all very funny that you don't find the Milne characters working in 3D when they started out as stuffed toys! As I've said around here in a previous Pooh/CG thread, and in my Tigger And Pooh review on the site, these characters work as good as any in CG because they were 3D models to start with. Now, I'm all for the "book illustrations" of the hand-drawn films - indeed, the Pooh films are always one of my points when I say what was great about the Xerox process - but in Pooh's case there's room for both, and the long-running franchise has appeared in many configurations over the years, from stuffed models, to animation, puppets, costumed characters (not just in the parks) and, now, CG...and bearing in mind the pre-school aims of these things, they've all worked.
Remember...this comes from a BIG, genuine fan of the original Pooh films ("Many Adventures", "Tigger Movie" and some of the bettwe "New Adventures", but not so much the endless TV-quality features) who was also genuinely surprised by the quality of the Tigger And Pooh series. It's not aimed at everyone, but as someone involved with a prior educational kids series, what they've done with it is actually very clever and charming.
Back to Loggins...I hope too that there's a new traditional Tigger movie in the works, but I wouldn't hold my breath. From what I understand, the Mouse is pulling back from the Pooh business to build up some need for new content. On the other hand, a new Tigger movie - by the time it comes - might be the thing they're betting on to kick-start things again.
I guess we'll know in the spring, if Kenny Loggins' name shows up on "My Friends Tigger And Pooh And A Musical Too", or if this album comes along around then.
