Scarlett Johansson is in talk to join the Coen brothers' next big film project Hail Ceasar!. Jonah Hill also announced on Twitter that he has been cast in the film, saying, "Hail, Caesar! So damn excited to get to work with the Coen Brothers!"
They will join Josh Brolin, George Clooney, Channing Tatum, Tilda Swinton, and Ralph Fiennes, who has also been in negotiations to co-star.
The film follows a 1950s Hollywood fixer named Eddie Mannix who is working to keep a studio’s stars in line. If cast, Johansson will play an actress "who suddenly becomes pregnant as her film is about to go into production." Hill's part in the story has not been revealed yet.
The film is expected to go into production this fall. Here's a more detailed description of the story from the initial announcement:
"The famed 1950s private investigator who worked for Confidential magazine and was the muckraker of the time using wiretaps to spy on movie stars and gather dirt. Otash was a former lifeguard who became a cop, then helped operate a call girl ring and lost his job as a cop and became a private eye who wiretapped… It was not unusual during the time for studios’ internal security to protect their assets to construct and manage the squeaky clean image of their stars. The big stars of the day were under contracts for a certain number of pictures so the powerful studios had their own go-to guys (and sometimes hired outside investigators) to deep-six scandalous stories, whether it be romantic dalliances, drug use, DUIs, arrests, you name it. For the more serious threats, the fixers used pay-outs, strong-arming, and took care of 'problems' (real or perceived) by any means necessary. It was the day of the old Hollywood star system."
