Was she the radiantly beautiful pop princess who earned the love of mainstream America with enduring hits like I Will Always Love You? Was she the down-to-Earth onetime gospel singer from the 'hood in Newark who couldn't believe when the crowd at the 1989 Soul Train Awards booed her as a sellout to black music? Or was she the unstable celebrity struggling with drug problems and an enabling husband, let down by those closest to her and isolated by her fame?

The new documentary film Whitney. 'Can I Be Me' suggests that the struggle to balance all of these issues and more — an identity crisis of superstar proportions — helped lead to the death of one of the best singers in pop music.

The movie opens in theaters today and airs on Showtime next Friday. It channels the voices of friends, backing musicians, former record company staffers and ex-employees to tell an intimate, tragic story. 'Success doesn't change you; fame does,' Houston says in a 1996 interview featured in the film. 'You got a whole world of people calling your name and you really don't know them. [Do people think] when we become famous that we have these beautiful perfect lives and nothing is ever on a low? It's a bad conception, because.

Money doesn't make you happy. It never did.' 'Can I Be Me' offers a story that references how race and class work in America, presenting Houston as a superstar whose early success locked her into a public image seriously at odds with her real life.

There are other stories. An old friend notes she and Houston used drugs together as teenagers. Lucy Schwartz Winter In June Rar here. A former bodyguard says he was fired when he tried to alert Houston's managers to rampant drug use by the singer and those around her. Another friend says Houston's husband, bad boy R&B singer Bobby Brown, wasn't faithful and intensified their use of substances. There's even an interview with Burt Bacharach, who helped lead the orchestra for the 72nd Academy Awards broadcast in 2000. He says Houston was yanked from the performing lineup of that show when she seemed erratic and unpredictable during rehearsals.

'It was like a train wreck. Kinda startling,' Bacharach says. 'It was so dangerous.

This is live television.[If] she sang the wrong song, nobody would know what to do. Ray Charles wouldn't know how to cover that.' The film suggests that, when Crawford exited the singer's life after one too many arguments with Bobby Brown, Houston's drug use accelerated. She accidentally drowned in a hotel bathtub on Feb. The biggest problem here: Because the film is unauthorized by Houston's estate, Broomfield and Dolezal lack access to the most crucial people in her story.

There are no original interviews with Clive Davis, Bobby Brown or Houston's mother Cissy Houston; they appear in clips from other media outlets. There is never-before-seen backstage footage from the singer's 1999 world tour and interviews with Crawford recorded then, but no recent footage.

Still, Whitney. 'Can I Be Me provides a compelling portrait of a supreme talent isolated by fame, dysfunctional relationships and a crushing drug habit, slowly diminished by the same qualities that originally made her a superstar.
