Scarlett Johansson Hot In a Toga; Scarlett Johansson and Jonah Hill Join Coen Brothers’ All-Star `Hail Caesar’ Starring George Clooney and Josh Brolin

Scarlett Johansson won't really be wearing a toga in her upcoming flick, but we'd like to picture it. Johansson would look good, to paraphrase Clare Boothe Luce, in a burlap bag, which is essentially a toga, right?

It was announced today by Variety, which generally knows what they're taking about, that Scarlett Johansson and Jonah Hill have signed on to join Joel and Ethan Coen's upcoming movie, "Hail Caesar!"

Funnyman Jonah Hill took to Twitter to proclaim "Hail, Caesar! So damn excited to get to work with the Coen Brothers!"

Scarlett Johansson and Jonah Hill join an already all-star line-up that stars George Clooney and Josh Brolin and will feature Channing Tatum, Tilda Swinton and Ralph Fiennes.

"Hail Caesar!" is set in the 1950s where Eddie Mannix (Clooney) is a Hollywood fixer who keeps stars out of trouble for the studios. Josh Brolin is set to play publicity head Howard Strickling, Ralph Fiennes as studio director Laurence Lorenz, Tilda Swinton has been cast as gossip columnist Hedda Hopper. Channing Tatum will play a Gene Kelly-type star.

Johansson would play a young actress that gets pregnant. Johansson announced in March that she is pregnant. Scarlett Johansson is engaged to Romain Dauriac.

The film will be Johansson's first collaboration with the Coen brothers since "The Man Who Wasn't There" from 2003. This will be the fourth time Clooney will be joining the Coens since 2000′s "O Brother! Where Art Thou?" This is the third time Brolin has worked with the directing brothers. He starred in the remake of the John Wayne/Glenn Campbell classic "True Grit" and the Oscar-winning "No Country for Old Men."

Production on "Hail Caesar!" is set to begin this fall. There has been no release date set.
