After warming up by directing a couple of episodes of House of Lies, Don Cheadle dove headfirst into his first feature film with a biopic about legendary jazz musician Miles Davis. Adding to the degree of difficulty, Cheadle isn’t just behind the camera but also in front of it too. The movie was acquired by Sony Pictures Classics prior to its premiere at the New York Film Festival last year where it received mostly positive, if not entirely glowing, reviews. At the time it seemed like an obvious awards contender, but based on the first trailer and new spring release date that may not be in the cards after all. Miles Ahead co-stars Ewan McGregor, Emayatzy Corinealdi and Michael Stuhlbarg and it hits select theatres on April 1st; check out the trailer after the jump and see what you think.
