Hundred bucks says in some way or form it ends up protesting the war in Iraq.
"Oh hey, we wanna make a film that protests the war in Iraq... what do we do?!"
"Umm... The Day The Earth Stood Still did that for the cold war... maybe we could do something like that..."
"Or maybe we... COULD DO THAT!"
They did say Gort is in the film. They said that after exploring different options they went back to the original presentation for Gort. So atleast they are keeping that :/
