Who's The New Jackie O?

Natalie Portman has been cast as Jackie Kennedy in a new film about the famous First Lady.

The film, which so far only has Portman confirmed to star, is being billed on IMDB as "an account of the days of First Lady, Jacqueline Kennedy, in immediate aftermath of John F. Kennedy's assassination in 1963". Darren Aronofsky, who directed Portman in Black Swan, is producing the film - the screenplay of which is by Noah Oppenheim - while Pablo Larrain will direct.

Back in 2010 Rachel Weisz was originally slated to play the part when she was engaged to Aronofsky, but allegedly dropped out of the project when they went their separate ways. "It's a very beautiful script," Weisz  told MTV at the time. "I think it's the four or five days after the assassination and how [Jackie] deals with the assassination and the funeral. It's not a biopic. Its about that short period of time."
