The "A Voice Within" video opens with a close-up of Aguilera's face and falls back to her sitting on a block in an abandoned prop room. Wearing a simple slip, she strolls around the room and eventually out of the building to the streets.
"I really love neo-realist and that's where I got the idea for the clothes, the styling and the texture of the film," the director said, naming filmmakers Pier Paolo Pasolini and Vittorio De Sica as influences. "She looks like one of those women in those films, like [De Sica's] "Two Women," with Sophia Loren running across the country in bare feet, that kind of idea."
LaChapelle actually shot the video in a deserted theater in downtown Los Angeles. The props were already there, with the exception of the light box he built outside that Aguilera lays on at the end.
"Light boxes are in my vocabulary as a photographer, so to speak," he said. "I love things that are contained. Basically, it's a bed of light. The whole video is sort of a journey and it sort of climaxes and then she goes to sleep."
The video was filmed by a Steadicam operator who walked backwards and eventually on to a crane for the finale. After carefully mapping out the path, LaChapelle rehearsed with a stand-in.
"When we walked through it, we did not think it was going to work," he remembered. "I was like, 'Oh my god, what have I done?' And then Christina did it the first time without a rehearsal; she nailed it. She brought so much energy and this passion, this f---ing craziness to it, spinning around. I knew I'd done the right thing."
LaChapelle and Aguilera did several more takes, but only one was as good as the first. They went with take five, but "it was a toss-up."
"Christina's someone who is really interested in art and artists and it's a nice experience because she respects the edit, the cut and the people who work on it," LaChapelle said. "It's not about showing a particular side of her face. She's not neurotic like that. She wants interesting imagery.
"This video is tailor-made for her," he added. "As simple as it is, there's not a lot of artists who could do that sort of video."
