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."
