Hail, Caesar! is a 2016 black comedy mystery film written, produced, edited, and directed by the brothers Joel and Ethan Coen. An American-British co-production, the film stars Josh Brolin, George Clooney, Alden Ehrenreich, Ralph Fiennes, Jonah Hill, Scarlett Johansson, Frances McDormand, Tilda Swinton, and Channing Tatum, with Michael Gambon as the narrator. It is a fictional story that follows the real-life studio fixer Eddie Mannix (Brolin), working in the Hollywood film industry in the 1950s, trying to discover what happened to a star actor during the filming of a biblical epic.

First talked about by the Coens in 2004, Hail, Caesar! was originally to take place in the 1920s and follow actors performing a play about ancient Rome. The Coens shelved the idea until late-2013. Principal photography for the film began in November 2014 in Los Angeles, California. The film premiered at the Regency Village Theater in Los Angeles on February 1, 2016, and was theatrically released by Universal Pictures on February 5.

Hail, Caesar! grossed $63 million worldwide on a $22 million budget and received positive reviews from critics. The film was chosen by National Board of Review as one of the top ten films of 2016, and received Production Design nominations at the 89th Academy Awards and 70th British Academy Film Awards.
