Over thirty buildings were prefabricated in Los Angeles and shipped to the site. Four Boeing CH-47 Chinooks were loaned out for four days. Outside shots of a tunnel were done in the desert, while the cavernous insides of the Hypocenter were fashioned on Warner Soundstage 16, their largest, with 32,130 square feet. Tenet wrapped on November 12, after 96 days of shooting.
