Production on The Batman has been paused after Robert Pattinson, the film’s star, tested positive for COVID-19.

On Thursday, Warner Bros. announced that the movie would temporarily halt production after a member of the crew tested positive.

“A member of ‘The Batman’ production has tested positive for COVID-19 and is isolating in accordance with established protocols,” a Warner Bros. spokesperson told Variety in a statement. “Filming is temporarily paused.”

A source familiar to the situation confirmed to Variety that it was Pattinson who had tested positive, though Warner Bros. nor the actor himself have confirmed the reporting.

The Batman, which has been shooting in the United Kingdom, had already paused filming in March when the COVID-19 pandemic hit, after only shooting for about seven weeks. The director Matt Reeves had reportedly hoped to finish shooting the movie by the end of this year after returning to filming a few days ago, but fans worry Pattinson’s diagnosis may push the movie’s release back. The movie had already been rescheduled once, with Warner Bros. now planning on releasing the movie on October 1, 2021.

Those who had been in contact with Pattinson, including cast and crew, have gone into a mandatory two-week isolation, but construction of sets and props has continued at Warner Bros. Studios in Leavesden, U.K.. The studio has also been performing contact tracing.

Other movie studios have also restarted productions on their blockbusters, though filming in California continues to be shut down due to the state’s high number of COVID-19 cases. The next Jurassic World movie from Universal Studios has been filming in the U.K., Avatar has been shooting in New Zealand and an Uncharted adaption has been in production in Berlin.
