In the 90s, George Clooney was as well known for his Caesar haircut as anything else, only rivaling Jennifer Aniston when it came to most talked about styles of that decade. He brings the look back in the first Hail Caesar set photos. And this time, he's also dressing the part.

Hail Caesar marks George Clooney's fourth time collaborating with iconic filmmaking duo The Coen Brothers. The film will bring an end to their 'Idiot Quadrilogy', which began with O Brother, Where Art Thou? in 2001, followed by Intolerable Cruelty in 2003 and Burn After Reading in 2008. Don't expect a sword and sandals epic, though. This latest caper from Joel and Ethan Coen is a period comedy revolving around the Golden Age of Hollywood.

Taking place over the course of a single day, Hail Caesar follows a Los Angeles fixer who sets out to solve a whole lot of problems for the city's biggest names before the tabloids can get their hands on the information. The all-star ensemble cast also includes Josh Brolin, Channing Tatum, Ralph Fiennes, Tilda Swinton, Scarlett Johansson and Jonah Hill.
