Oh, well I'm not sure how accurate this is. It's sort of friend of a friend kind of stuff from a friend from my old animation/illustration school days that actually made it and has worked on some very cool, very big projects. I trust him, though who knows how accurate his information might be.
I don't know if this is true, if it's from an old rejected pitch or from a newer one. I don't know how to verify this, or if you even could. I took this with a grain of salt and I'd recommend you do too.
We were talking about comics and the Dark Knight and he mentioned that there were some details floating around about the next Superman movie. They are as follows:
1) He told me that there was going to be a big alien alien machine (we both figured this to be Brainiac) that was going to come to Earth after the events of the first movie looking for Kryptonian technology or Kryptonians.
2) That "Brainiac" was going to come after Superman and Jason and that Lois and Jason would be put in danger again. I don't know if anybody dies or, specifically, if Jason or Richard are killed. He didn't mention Richard at all though so maybe he's gone?
3) He also said that Lex was going to be in it too, that he was going to get a get out of jail free card for helping to save the world from Brainiac.
4) There'd also be a sequence in space (RTK?) and a big battle in the city between Superman and a bunch of alien robots.
So yeah, that's what I've heard. Again, how true it is, I've no idea. Has anybody else heard anything along these lines? Anything similar?
