lol, its sad though, I have a feeling that the movie might turn out good, and ruin all our ideas...=D
They could have it so when aslan roars, he would say "you might want to cover your ears", and then the roar would come out as a meow...
or they could have it revolve around one of the islands they visit, and leave out everything else out completely. like Deathwater island. Ed, Lu, and Eustace go through a picture of a creek land on the hill. Lucy says she thinks they aren't in England anymore. Ed rolls into deathwater, and his hand turns to gold. They meet Caspian and his crew, who got shipwrecked there (enter ES Gilligan island theme song), who all start fighting over Eds hand. they want to cut it off, ed stops them, shuns them for being greedy, and then they try to get the gold to get off his hand...ect.
