I agree with the Wizard of Oz, did anyone see Tin Man, it was a made for sci-fi thing and it was actually quite good, if it had a bigger budget, I think it could be pretty badass. I'd also like to see it take a darker direction, those books, while note really dark aren't really light either. Something in the vein of Return to Oz would be cool.
For the Godzilla guys, I'm sure you knew this, but the Japanese call our remake GINO, which is Godzilla In Name Only. Also, in Godzilla: Final Wars the fight between Godzilla and GINO lasts 13 seconds, which is the shortest fight ever. Also, the chapter title on the dvd is called like Pretender to the Throne or something, its kinda funny how dismissive they are about it, can't say I blame them.
I know this might sound like blasphemy, the original is great, but The Dirty Dozen could be a cool remake, it would all depend on the cast, but I think you could do it.
