Robert Downey Jr. is negotiating a deal to star in the 3D sci-fi film Gravity.

Downey will play the leader of a team posted at a remote space station. While he and a female colleague are travelling outside the space station, the other team members are decimated by debris from an exploded satellite.

Alfonso Cuaron (Children of Men) will direct a script he co-wrote with his son, Jonas.
