Don Cheadle's Miles Davis drama biopic has been years in the making and the first official trailer is finally here, following a world premiere at the New York Film Festival last fall.

Alongside Cheadle, Ewan McGregor is playing a shaggy-headed Rolling Stone reporter named Dave Braden who conspires with Davis to steal back his session tapes, while Emayatzy Corinealdi plays Davis' first wife, Frances Taylor.
