Photo offers rare glimpse into Apple's design studio

"We did a follow-up interview with Jony Ive at Apple in California last week, and enjoyed the opportunity of filming inside Apple's design facilities," Hustwit wrote on a website promoting an upcoming film.

"I felt like Charlie in Willy Wonka and the Chocolate Factory," he added, "except everything was made of shiny aluminum instead of candy.  And there were no oompa loompas."

Hustwit is working on a documentary called Objectified that will examine industrial design.  The film is described as "a look at the creativity at work behind everything from toothbrushes to tech gadgets."

Hustwit's other credits include a documentary about the band Wilco, one filmed during a Death Cab for Cutie tour, and another documentary about electronic music pioneer Robert Moog.

His documentary about graphic design and typography, Helvetica, premiered in 2007.
