Meanwhile, Atomic Fiction, which completed nearly 100 shots of cities (including Shanghai) and vehicles, offers a lower-cost business model utilizing cloud computing and other measures. Atomic has been working with a company called ZYNC to utilize Amazon's EC2 cloud services. By moving rendering to the cloud instead of owning the computers, they treat rendering like a utility and only pay for what they use.This means that rendering can literally be scaled from as many cores as you need for a particular job, back down to the Macs on the artists' desks between gigs.

"We established some new ground rules for the look of things," offers Atomic co-owner and VFX supervisor Ryan Tudhope. "This included finding common elements such as graffiti, shelters/tents, antennas, and camp fires to tie our shots together and, more importantly, give 'Looper's' cityscapes their own signature feel.

"Rian chose to shoot the film on anamorphic 35mm, which was (mostly) a blessing. The plates are beautiful and grungy, with blue anamorphic lens stripes, lens distortion, and heavy chromatic aberration around the edges of the frame. The downside, of course, is that all these lens artifacts made the work more complicated. For example, the lenses produce an extreme warping and 'scaling' at the edge of frame during focus pulls, while the center of the image remains unaffected. In the end, we tackled each challenge by building custom scripts (in Nuke) that would re-create these artifacts on our CG elements or matte paintings and could be rolled out to the entire team."

Working on "Looper" was a smart move for these VFXers and it's only going to mean the opportunity for bigger and bigger films with the director down the road.

"And it turned out to be a good movie," Goulekas says. "Quite often, we work on big movies and the visual effects are good but the movie isn't received well for whatever reason and it gets disheartening. It's one of those movies where you're still thinking about it and you talk to your friends. 'So when this happened, did you think it was because of this, or was it meant to be that?' It prompts discussion afterwards, which is cool."
