After years of being captured by cameras, Entourage star Adrian Grenier turns his lenses back on the photographers in the documentary Teenage Paparazzo.

The film follows 14-year-old paparazzo Austin Visschedyk, who Grenier uses as his ticket into a circle that's closed off to outsiders. "He was a perfect way to infiltrate the paparazzi because he wasn't jaded and was open to the change," But he also makes it clear the documentary isn't about exploiting the paparazzi to paint them in a negative light. "I was really looking to find a constructive understanding of who they are," he says.

The 34-year-old talks about why his friends weren't originally on board for the project, how the experience changed his perception of his own fame, and what he hopes people will take away from the film. Plus: What does he think about an Entourage movie?
