Despite the insane stakes, this year's Blade Runner 2049 lived up to (and in some ways surpassed) the paradigm-shifting original film. The sequel created its gritty futuristic look with the help of plenty of visual effects, but building settings isn't all the film pulled off with digital wizardry. A shocking moment comes with the kinda-return of (*spoilers*) Sean Young's replicant Rachel, who looks like she hasn't aged a day. The company behind that VFX trick just released a trailer giving a peek at exactly how they did it.
