With shooting set to begin in less than a month, Hail Caesar directors Joel Coen and Ethan Coen have added Patrick Fischler, David Krumholtz, Fisher Stevens and Clancy Brown to the cast.

The plot is set in 1950s Hollywood and centers on Eddie Mannix (George Clooney), a "fixer" who works with all of the major movie studios to keep the stars in line and to cover up any scandals. He is tasked with tracking down a major movie star who suddenly disappears in the middle of shooting a new movie. Patrick Fischler, David Krumholtz and Fisher Stevens are playing Hollywood screenwriters who are also Communists, while Clancy Brown plays an actor in the movie-within-a-movie, dubbed Hail Caesar.

This quartet of actors join an all-star cast that also includes Josh Brolin, Channing Tatum, Ralph Fiennes, Tilda Swinton, Scarlett Johansson, Jonah Hill and Alden Ehrenreich.
