Lily Rose-Depp and Natalie Portman Speak to the Dead in 'Planetarium'

Set in prewar Paris, Planetarium tells the story of two American sisters who can communicate with the dead. Mesmerized by their abilities (and beauty, no doubt), a big-time producer played by Emmanuel Salinger offers to cast them in his film. The closer the sisters get to the man, the darker their lives get. Directed by Rebecca Zlotowski, Planetarium premieres at the Venice and Toronto Film Festivals in September and has yet to get a U.S. release date. Watch above for a first look at the nostalgic 1930s psycho-drama.
