I've posted on this to some extent in my own journal but I think that the whole concept of re-makes is totally backwards. Instead of remaking beloved classics, hollywood needs to start remaking movies that weren't that good the first time. There are a lot of movies that would've been good with a better director or script or actors or even editor. Why not remake those? You compare a remake to a classic and the remake almost always pales in comparison, but if you remake a failure, you're golden. For example:
Ishtar. Remake it with Luke and Owen Wilson. It would be perfect for today's considerably more middle-east savy audience.
Night of the Lepus. Could any remake of this movie be worse than the original? I don't think so. I'd say cast Dennis Hopper in the DeForest Kelly role.
Actually, I'd like to see all of the b-movie atomic test giant animal movies remade with modern special effects.
Guys And Dolls. Face it, this could've been a great movie if they'd gone ahead and made it as a Rat Pack flick but Brando ruins the whole thing. You could have Kevin Spacey and Harry Connick Jr. as Sky Masterson and Nathan Detroit.
X the man with the X-Ray Eyes, I'd like to see Steve Buscemi in an NC-17 version of this classic. It'd just be chock full of gratuitous nudity and skeletons. With Christopher Walken in the Don Rickles role.
I am ESPECALLY fond of your idea of Guys and Dolls being remade. That would be FANTASTIC. With someone cute like Kristen Chenowith in it.. it'd be greaet. You should pitch that. I bet they'd go for it.
