A little under two weeks later, WB moved Tenet again to August 12, and by the end of July, the studio landed on the final release model: opening in 70 international countries starting August 26, followed by a gradual U.S. rollout starting September 3, though that was preceded by three days of preview screenings and a first-weekend start in Canada.
Had 2020 gone as planned, Tenet would have opened on July 17, but by June, approximately three months after movies started being postponed due to COVID-19, Warner Bros decided to shift Christopher Nolan’s latest feature to July 31.
