Iconic reggae superstar Bob Marley’s too-brief life is chronicled in this documentary lovefest. Though he died from cancer at age 36 in 1981, his music and his influence live on. Loaded with rare footage, performances and interviews, the 2012 film also discusses Marley’s infidelities, even though it’s made with his family’s cooperation. It’s directed by Kevin Macdonald, best known for his dramas “The Last King of Scotland” and “State of Play.” PG-13, 145 minutes. Extras: interviews, photos and director commentary.
