You don't need a StereoMirror to see this film, but it probably could have helped during production. 3ality Digital did the production work, including the sophisticated stereoscopic camera set-up. We look forward to seeing this one when it's released at Sundance.

"Previous generations of 3D film relied heavily on gimmicks, and the limits of the technology resulted in eyestrain--diminishing the life-like qualities," according to production company 3ality Digital, which, in an overview posted at the film's website, said it was shot using "cutting-edge technologies ... from artificial intelligence that aligns 'eye position' of a stereoscopic camera in real time, to first-ever high-res 3D systems with zoom lenses, robotic control, and integrated digital processing."
