Channing Tatum, Ralph Fiennes and Tilda Swinton are in talks to board Hail, Caesar!, joining George Clooney and Josh Brolin in the Coen brothers' old-Hollywood comedy.

Clooney stars as Eddie Mannix, the real-life 1950s Hollywood fixer who ensured MGM's marquee names didn't find their way into the gossip rags because of their-less-than-wholesome behavior. According to The Hollywood Reporter, Tatum would play a Gene Kelly-type star, while Fiennes would portray director Laurence Lorenz, and Swinton legendary gossip columnist Hedda Hopper.

Hail, Caesar! does not yet have a set release date.
