Production designer Eugenio Zanetti transformed a decommissioned aircraft carrier into a portion of the Shores of Hell. To illuminate the enormous carrier — a nighttime setup in a San Francisco shipyard — Serra deployed five 15' helium balloons fitted with four 4K HMI lamps. The cameraman expounds, "The balloons were controllable, very easy to use, and very useful for creating a relatively soft top light in a big area. I also used fire and flares as practical sources, though not close enough to the actors to make it dangerous."
