It appears fans may have to wait a bit longer for Aquaman and the Lost Kingdom, Dune: Part Two, and The Color Purple as Warner Bros. is considering delaying the respective films due to the Writers Guild of America and SAG-AFTRA strikes. Most of Hollywood is currently on pause as the WGA and SAG-AFTRA are currently on strike, following failed negotiations with the Alliance of Motion Picture and Television Producers for better terms. The WGA strike has been ongoing since May, while SAG-AFTRA commenced theirs as of July, which is affecting every Hollywood studio, including Warner Bros.
