The Coen brothers, a sibling duo of filmmakers, are known for their frequent collaborations with various actors and film crew members.
They have also worked three times with Michael Badalucco, Josh Brolin, Richard Jenkins, and J. K. Simmons, and twice each with Tim Blake Nelson, Jeff Bridges, Clancy Brown, Charles Durning, Brendan Gleeson, Holly Hunter, Ralph Ineson, Scarlett Johansson, John Mahoney, Jefferson Mays, Elizabeth Marvel, Harry Melling, Tony Shalhoub, Peter Stormare, Tilda Swinton, Billy Bob Thornton, and M. Emmet Walsh.
The Coens similarly tend to collaborate with certain filmmakers as well, especially Roger Deakins, Jess Gonchor, Skip Lievsay, and Mary Zophres.
(Both films are set in blindingly white snow, which reflects much light and can make metering for a correct exposure tricky).
[3] Carter Burwell has scored all of the Coens' films, aside from Crimewave (1985), although T Bone Burnett produced much of the traditional music in O Brother, Where Art Thou?
