GATTACA star Niccol signed Hawke and Ewan McGregor to star in the film - but it wasn't violent enough to pass studio approval.
Hawke says, "I think Andrew ought to be permanently funded. He has this beautiful futuristic movie that's a metaphor for the Israel-Palestine issue - it's an incredible script - and Ewan McGregor and I wanted to do it, and there was no way we could get the movie done.
"There's not enough violence in it, if you can believe that.
"It's the violence that gets the movie made."
