I grew up on Fraggle Rock and the idea of a movie without Jerry, Steve, Karen, Dave and Kathryn as the Fraggle Five makes me sad. I also think that if the original performers were involved, then they would be able to retain the integrity of Fraggle Rock and be able to keep the script writers in check if they try to go all..."Hannah Montana" on us.
I would love to see this film, but I am wary of how it might turn out. I haven't seen Indiana Jones 4 because I heard it was so bad, or the Harry Potter movies, the new Star Wars movies took something away from the originals...etc. Would hate to see the Fraggles go the same way!
When and whatever circumstances come together and the film DOES get made (that's pretty hopeful, but not too sounding) There is NO DOUBT that we'd see the puppeteers leap onto it. Karen is always looking for an excuse to play Red (she actually performed her live for Comic-Con and the Dr. Doozer event)... any problems would lie on the availability of Steve Whitmire and Dave Golez in the event that it bumps heads with any Muppet Show related project. Jerry would ad LEAST loop dialogue (he's not as young as he used to be, and he really can't puppeteer anymore)... I'm sure Katheryn Mullen would love to play Mokey again (she's doing absolutely beautiful charity work Jim would be proud of). The only thing is Richard Hunt passed on years ago, but David Rudman has taken over most of his roles just wonderfully.
As for the other things I'm gonna address.... Corey Edwards (the screenwriter of the movie) has stated passionately for the past couple years that it will be as true as it can be to the original show, only tweaking slight things to make it fit in a movie. No Shrek pop culture references... no tween pop... he's struggling to make us all happy.
Secondly, I'm SO SICK of people saying "New Stuff doesn't hold up to the old stuff." That's nostalgic bias. For me, the reason the new Star Wars films don't hold up is because in between 1977 and 2005, Lucas became a cranky old fussbudget that thought CGI is THE end all be all, fooling his younger self into thinking it really wanted that. Indiana Jones 4, same thing... Spielberg is an old fussbudget. But I really think when you get bright, new blood into a project... one with vision and respect for the original, you'll have gold. Why, The last 2 Batman movies blew even the Tim Burton ones out of the water for me. I'm sure that very little has changed in the Fraggle Holes... they barely know about "Silly Creatures" so a Fraggle popping out of a hole could experience the same feeling if they popped out in 1957, 1985, 2039... Their culture hasn't changed the way ours has, and anything will be new to them.
