Filmmaker Spike Lee is putting the finishing touches on a documentary about Michael Jackson. The film, which focuses on the late singer’s 1987 album “Bad” and its accompanying world tour, features Lee’s interviews with members of Jackson’s collaborators and tour team as well as interviews with contemporary stars like rapper Kanye West and Sheryl Crow, who was a backup singer on Jackson’s “Bad” tour.

Lee says in a statement he’s “a huge fan of Michael Jackson’s” and cares deeply about his legacy.

He adds that the project allowed him to uncover “just what made this a huge, important coming of age” in Jackson’s career.

There’s been no announcement of an official release date for Lee’s documentary but it is expected to be released around the same time as the September 18th release of the box set “Bad 25” which will celebrate the 25th anniversary of Jackson’s “Bad” album. Lee previously directed the clip for Jackson’s posthumous song “This Is It,” released months after the singer’s death in 2009.
