Hot on the heels of some passionate festival buzz for her turn in the upcoming ballet film Black Swan, Natalie Portman has reportedly been offered the lead role in Warner Bros.’ 3-D drama Gravity, according to The Hollywood Reporter. The $80 million film, which is being directed by Alfonso Cuarón (Children of Men, Y tu mamá también), is a survival story about a woman who’s stranded on a space station and her attempts to return home to Earth. The role was previously turned down by Angelina Jolie, and Scarlett Johansson and Blake Lively were later rumored to be competing for the gig. But Cuarón has now reportedly offered the part to Portman without requiring the actress to do a screen test. Portman is expected to make a decision soon after reading the latest version of the script. Robert Downey Jr. has already signed on for a supporting role in the movie, which is scheduled to shoot early next year.
