Channing Tatum, Tilda Swinton and Ralph Fiennes join Coens' Hail Caesar

The Coen brothers' next directorial project has added three big names to its cast list, with Channing Tatum, Tilda Swinton and Ralph Fiennes all signing on for Hail Caesar .

The casting comes hot on the heels of last week's announcement that Josh Brolin would be taking a starring role in the project, which is putting together quite the ensemble.

Set in 1950s Hollywood, the film will follow the exploits of a "fixer" for the great and good of Tinseltown, a part thought to have been earmarked for Brolin.

According to THR , Tatum will play a star in the mould of Gene Kelly, while Fiennes will play a studio director and Swinton a powerful Hollywood gossip columnist.

The comedy will begin filming this year, ahead of a likely 2015 release date. It's already shaping up to be one of the starriest films of the year...
