Arnold Schwarzenegger was offered the lead role.
The script was black listed a few years ago from the guild. Alexander Borukhov picked it up and revised it with the help of JJ. Abrams.
Alexander Borukhov claimed that one of the reasons why he wanted to make this film R-rated was that he was tired of having to work within the confines of the PG-13 rating.
Alexander offered JJ. Abrams a director position. He turned it down due to the timing of Star Wars being filmed.
