The trailer for Christopher Nolan next movie, Tenet made a surprise appearance in theaters Thursday night.

A 40-second teaser screened ahead of preview showings of  Hobbs & Shaw. The trailer has not been released online and it is unclear on when it will.

According to social media reports, the teaser only shows star John David Washington, along with the tagline “It’s time for a new protagonist.”

The secret theater debut doesn’t come as too much of a surprise when it comes to Nolan, who has long been a proponent of the theatrical experience. He’s refused to go the way of many other prominent filmmakers and debut his movies on Netflix,

The first trailer for Dunkirk premiered in theaters ahead of Suicide Squad before landing online days later, and it’s all part of Nolan’s push to getting people to see movies in actual theaters. 

Starring Robert Pattinson, Elizabeth Debicki, Dimple Kapadia, John David Washington, Michael Caine, Tenet is slated for release in theaters on July 17, 2020.
