Don Cheadle (Crash, Iron Man 2) directs and stars in this somewhat rickety look at the life of jazz legend Miles Davis. Riffing, freeform style (it's like jazz, man!), the film wanders around various points in Davis' life. Most of it takes place in the late-'70s as a drug-addled Davis is interviewed by a tenacious reporter (Ewan McGregor). Amid the impressionistic flashbacks, the film morphs into a buddy action caper with the musician and the reporter teaming up to steal back some missing recording tapes. That probably didn't happen.100 minutes R.
