A new teaser trailer has been released for the upcoming Whitney Houston documentary, Whitney. The film will provide an in-depth look at the life and career of the late superstar from the point of view of her family and close friends.

“I Have Nothing,” the Oscar-nominated song from the film The Bodyguard, is featured in the trailer. Clips of Houston’s private life, including her childhood, behind the scenes of concerts, music videos and interviews, are played between shots of her loved ones describing her talent and impact. With regard to her singing ability, her mother, Cissy Houston says, “You have three places to sing from: heart, mind, guts. She learned them all.”

Despite her stardom, Houston lived a “simple” life, and the documentary alludes to her falling to the pressures of fame. The Kevin Macdonald-directed film takes a look at the woman with the big voice. According to the trailer, “You don’t know her story until you hear the truth.”

Whitney will premiere at Cannes Film Festival before its release in the United States on July 6.
