I think we're all saying the same thing.... The integrity of all parties has to be there. Disney can't harm the future of the Muppets, which like it or not is in their hands. Empire can't harm the past which they've taken responsibility of.
Personally, the movie's a great idea. Realistically, though, a movie to recreate the past is hard. Doing it to recreate real celebrities/ idols is harder. To completly remake an entire cast of beloved characters and the people performing them (to my knowledge) has never even been done. It seems hard. But let's not forget that we're dealing with a man who could get a frog on a bike, a pig to swim, and a bird to bring peace to a foreign country. Simple is good, and nothing is impossible!
Also, as much as I don't feel he particuarly has the maturity to handle the role, I thought of a person who may beable to take on Caroll Spinney. He may be too short, but David Spade really has some of the same features that Caroll has, especially from Sesame Street's early years. I can see him attempting the characters too; similar voices. Just an idea...
Opinions welcome. New ideas highly anticipated!
