Warner Bros.'s new 3D project Gravity has tumbled back to earth after Angelina Jolie passed on the project, which could put an indefinite hold on the movie. This news comes from Deadline New York.

It was reported that Angelina Jolie had actually passed on the Alfonso Cuarón project twice, the first time when the project was at Universal, and then again just recently, with the movie now at Warner Bros. Robert Downey Jr. is attached to star, but the site reports that his role isn't very big and that it wasn't Alfonso Cuarón's intention to make the film a starring vehicle for Robert Downey Jr.

Alfonso Cuarón intends to direct from a script he co-wrote with his son Jonás Cuarón. The story focuses on a remote space station. While Robert Downey Jr.'s character and a female colleague are outside the station doing research work, a field of debris kills their other team members. The main plot will center on the female character, who is trying to return home to her child.

Deadline New York also reports that Warner Bros. has approached Sandra Bullock and Natalie Portman to take on the role. The studio is keen on both actresses, but they have also approached a bevy of other talent as well, such as Naomi Watts, Marion Cotillard, Carey Mulligan, Scarlett Johansson, Sienna Miller, Abbie Cornish, Rebecca Hall, Olivia Wilde and Blake Lively.
