According to BBC News, the documentary covers not just the 1987 record, but also the record-breaking world tour and the highly-regarded music videos it spawned.
Notable stars interviewed for the documentary include Kanye West, Mariah Carey, and Sheryl Crow, who worked as a back-up singer on the 'Bad' tour.
Lee said: "We have footage in this documentary that no-one's ever seen - stuff that Michael shot himself and behind the scenes stuff."
He continued: "We had complete access to [his] vaults. He wrote 60 demos for the Bad record. Only 11 made it.
"We got to hear a lot of that stuff, too, so it was just a great experience."

Lee also stated that he hopes the film would show a more personal side to Jackson, with the 25th Hour director claiming he is "more than just a huge fan of Michael Jackson".
He added: "Having the chance to actually know him and work with him, I deeply care about his legacy."
Jackson passed away in 2009, with the third anniversary of his passing recently being honoured online by his daughter Paris.
The 13-year-old has expressed her ambition to follow in her father's footsteps and enter the entertainment industry herself as an actor.
