Sandra Bullock might become an astronaut -- at least for her next film role.
Though Natalie Portman was most recently in talks to star in the flick "Gravity," Bullock is now in negotiations instead -- and, if she takes the role, she'll play an astronaut stuck in space.
The movie was initially set up as a project for Angelina Jolie -- but, according to Variety, the studio wouldn't pay her $20 million fee.
If Sandra does star, it would be her first movie since splitting from husband Jesse James and winning the Oscar.
