Scarlett Johansson is reportedly in negotiations to star in a 3-D sci-fi movie that Angelina Jolie turned down. According to reports, the Match Point star has 'verbally agreed' to play the main role in Gravity from director Alfonso Cuarón. The film revolves around the adventures of lady who returns home to Earth and her daughter after a space mission fails. Scarlett's Iron-Man 2 costar Robert Downey Jr. is rumored to be her co-star in Gravity, too. Jolie apparently declined the offer because she didn’t want to share the screen with a leading man.
