Imagine watching “Tenet” at the movie theatre only to spot Tom Cruise in attendance, wearing a mask of course.

For some lucky fans across the pond, that’s exactly what happened this week.

Cruise posted a video of his visit to the cinema amid the COVID-19 pandemic in London, to see the new Christopher Nolan-directed thriller. He wrote: “Big Movie. Big Screen. Loved it.”

In the actor’s video, he can be seen at one point waving to fans that recognize him and questioning, “How did that happen? I’m wearing a mask.”

Fans excitedly posted on social media, revealing photos of the star taking in the film in the audience.

Cruise even posed for photos, masked and at a safe distance, with fans at the screening.
