It seems to me that we're in a bit of a catch 22...
Follow That Bird will more than likely be geared toward more of a 'Old School' generation of viewers. But unless there's a typewriter telling us that this edition isn't intended for today's pre-schoolers, it will probably be a bit kid-proof; hence an Elmo on the cover.
We probably won't be seeing any kind of interviews with puppeteers or filmamkers, as much as that pains me. The featurette will probably be along the lines of the 2 minute one from Elmo in Grouchland: character interviews and an explination of the plot. Hopefully, being that this is the 25th Anniversary (in the 40th Anniversary year) there will be a bit more depth... character commentaries would be incredible; in the eyes and ears of a preschooler anything more would just be "Who is that and why is he talking when Big Bird is; who taught him those manners, Gorgs? Wait, Gorgs?" I digress...
What might be neat is a "Big Bird's Photo Album" where you see pictures from on the set where Big Bird 'visited' as he traveled back to Sesame Street... This could be seen two ways "look at all those cool people Big Bird met" for the kids and "look at all those cool prople who got to meet Big Bird" for the adult fans.
Just a few thoughts... Can't wait to see all of this progress!
