Production began in May 2023 but was suspended in June 2023 due to the Writer's Guild of America strike. Production was set to resume after the end of the strike but was further delayed due to the SAG-AFTRA strike. With both strikes ending in September and November respectively, production resumed on December 12, 2023 and wrapped on January 14, 2024.
