A new documentary on legendary singer Whitney Houston is set debut at the 2016 Cannes Film Festival next month under the same British banner that introduced the Oscar-winning doc, Amy. So far, all signs point to it being well done with Oscar-winning director Kevin MacDonald (The Last King of Scotland) helming the film.

According to The Hollywood Reporter, the documentary will be an "unvarnished and authentic" look at the late pop icon's life and will "examine both the highs and lows of her dramatic career." It's also the only documentary to have been officially authorized by Houston's estate since her death.

Music mogul, Clive Davis, who is credited with bringing Houston to worldwide prominence was interviewed, as well as close friends and collaborators who are able to shed light on who Houston truly was, describing her as "both blessed and cursed with perhaps the greatest natural ability of any pop star in history."

The documentary will also feature never-before-seen footage which will showcase her entire life - from singing in the church choir to her tragic death. Exclusive demo recordings and rare performance will also be featured in the film.

It's no surprise that Houston's life is being spotlighted. The iconic songstress, who passed away in 2012, was under constant scrutiny, as she publicly struggled with drug addiction and depression. Despite her personal trials, there's no debating the late pop icon's impact on music and pop culture. She sold over 200 million records worldwide, and is the only singer to have had seven consecutive No. 1 Billboard Hot 100 hits. The Bodyguard, which she also starred in alongside Kevin Costner, remains one of the best-selling soundtracks of all time, spawned by Houston's emotional remake of "I Will Always Love You."

“The story that is never told about Whitney is just how brilliant she was as an artist; by many measures she had the greatest voice of the last 50 years," said Macdonald, who also said that like Amy, the documentary won't shy away from the darker parts of Houston's life, including her drug addiction. "She changed the way pop music was sung - bringing it back full circle to its blues and gospel roots. She was also completely unique in being a black pop star who sold in countries where black artists don’t traditionally sell."

One of the most beloved voices of the 20th century, The Whitney Houston's documentary should be inspiring to watch on the big screen.
