The Coens are adding even more star power to their latest film, with Tilda Swinton, Channing Tatum and Ralph Fiennes all negotiating to join George Clooney and Josh Brolin in Universal and Working Title's “Hail Caesar!” according to an individual close to the project, TheWrap said.

Joel and Ethan Coen are directing the film which follows Eddie Mannix, a studio executive and fixer in the Golden Age of Hollywood, whose job it was to keep the salacious private scandals of the town's biggest stars out of the press. Tatum will play a star, Fiennes a director and Swinton a gossip columnist.

Tatum is on screen now in “22 Jump Street” and Swinton is in this weekend's “Snowpiercer.” Fiennes last appeared with Swinton in “The Grand Budapest Hotel.”
