Cameron and his CAMERON | PACE group partner Vincent Pace shot the film with their Fusion 3D stereoscopic camera system, technology made famous on Avatar. Filmed in 37 days over three time periods beginning in October, 2010, Worlds Away presented numerous practical and logistic challenges for both filmmakers and performers. Cameron and Adamson were not looking to sit back and just film live shows in 3-D.  10 3-D cameras were employed, including Steadicams used to shoot close-ups right in the middle of performances.  Cameron himself would often dangle 50-100 feet in the air from high camera positions to capture that feeling of vertigo and danger that comes from performing 90 feet above the ground.  As Cameron described, "The live experience of these shows is incredible. But in the movie theater, what we can give you is the experience of being right in the middle of a show where you will really get to see the detailed work that's gone into the characters, the costumes and the choreography. There is pageantry to the live experience, but there is an intimacy to the 3-D experience."

Cameron continued, “Andrew had to walk a fine line working with such diverse elements from these shows. It was never meant to be about effects but to showcase the raw, pure physical human talent and their amazing ability. While it starts in this sort of run down circus, it plays out as discovery of this other dimensional circus world they fall into, but it is still very much a circus. There are wires, harnesses and you see it all, no effects hiding it. In seeing it, you experience the ingenuity of staging, costume design, the strength and agility of their talent that seem so effortless, so fluid. But the preparation and work that goes into it is anything but effortless. What you see is pure Cirque.”
