Rachel Weisz has been tapped to play iconic First Lady Jacqueline Kennedy Onassis in an upcoming biopic, Jackie. The film, which will be produced and directed by Weisz's fiancee Darren Aronofsky, follows Jackie during the four days in 1963 between President Kennedy's assassination and burial. No details about the movie's release are yet available, but one thing is for sure: We can't wait for Weisz's performance—or her costumes.
