While he may not be in the film, Tom Cruise loves a blockbuster movie and a surprise appearance, and the star got both when he crashed a London screening of Tenet on Tuesday.
"Big Movie. Big Screen. Loved it," Cruise tweeted of Christopher Nolan's film, along with a video of the experience.
In the clip, we see Cruise, well, cruise through a grey, rainy London in the back of a black cab on his way to the screening, wearing a black face mask.
At one stage he is recognised by fans while sat at traffic lights. He dutifully waves and asks, "How does that happen? I'm wearing a mask."
"Back to the movies," he says as he arrives at the cinema, posing by a poster for the film.
We then see Cruise inside the theatre, where he can be heard clapping as the film begins, along with other moviegoers. "It is great to be back in a movie theatre, everybody," he says.
He claps again as Nolan's epic ends, and as he leaves a fan asks if he enjoyed the film, to which he replies: "I loved it. I loved it."

Tenet is finally due for cinema release this weekend, after three delays. It was originally scheduled for a July release.
The thriller has been written and directed by Nolan, and stars Robert Pattinson, John David Washington, Elizabeth Debicki, Aaron Taylor-Johnson, Dimple Kapadia, Himesh Patel, Clemence Poesy, Michael Caine and Kenneth Branagh in key roles.
The film has been given very warm early reviews by critics. For The National, James Mottram gave the film 5/5, and described it as "a puzzle-box picture that's sprung from the steep trap that is Nolan's mind".
It is currently rated as 8.3/10 on IMDB and 83 per cent on Rotten Tomatoes, awaiting an audience score.
It is thought that Cruise is in London to film Mission: Impossible 7, which is due for a November 2022 release.
