It sounds like it could be really good. I like the bits with the Muppet Signal and the Slo-Mo.. And I would like to thinkthat Bale would do the cameo, I can just picture Gonzo stood next to him as Robin. Although I think, like was said in the review, they're gonna have to zest up some of the spoofs/cameos they have.. I think it would be pretty cool if they got like Michael Caine and Tim Curry involved in some sort of cameo, maybe helping the Muppets out putting on the show.
Oh.. They have to end the movie with either a pre or end credit scene, involving Statler and Waldorf saying something about the film. I dunno about you guys but surely, that's gotta be an obvious thing to do..
Oh and I know it's a bit un-related but seen as though it's been mentioned, I had an idea for a new Looney Toons film which has an old black and white cartoon character, who is bitter about the transition and popularity of colour, kidnapping Bugs and gathering other black and white characters to start invading the cartoons. When an animator (I see Zach Braff) stumbles upon this plot to take over, he rallies Daffy, Foghorn, Wyle E, Sylvestor and Porky to go save Bugs.
