Warner Brothers' 'Tenet' is a big-budget thriller from director Christopher Nolan.
Its release has been delayed several times due to the global crisis.
But it finally came out in 70 countries on Wednesday - including in the UK, where the studio will be looking very closely at the box office receipts.
Film critic Kaleem Aftab.
"I think if Tenet is a success, we'll see a quick rush of releases. We'll see Bond come out for sure in November. The worry is if Tenet's a flop, they'll decide to wait til next summer."
Of course, social distancing is the order of the day at your local cinema.
Whether you're buying your popcorn or watching the screen.
But the general manager of London's Odeon Luxe Leicester Square Tessa Street says she's confident moviegoers will return.
"It's obviously vitally important that Tenet's successful, and that we deliver a great experience for our guests so they want to come back, and they're waiting to see what is the next film and we're really confident that will be the case."
The movie will be released in the United States next week.
