Nearly all of China's 70,000 theaters are closed as the country reels from the coronavirus, and it has cost the local movie business over $1 billion.

Chinese ticket revenue is at just $3.9 million in the last 20 days, according to The Hollywood Reporter. Revenue hit $1.52 billion in the same timespan last year. The weekend of the Chinese New Year, which was in late January, is usually China's biggest time for moviegoing. It's also when major film releases were canceled and the theaters started to close.

Jimmy Wu, the CEO of Chinese cinema company Lumiere Pavilion, told THR that the Chinese government will have to take drastic measures to save the theater industry. They include offering emergency funding or a refund of the "film fee" from China's Film Bureau that is taken out of ticket revenue.

The coronavirus, which originated in the Chinese city of Wuhan and has spread to at least 25 more countries, has killed more than 1,100 people and infected more than 45,000.

Chinese regulations prevent Chinese movies from being released outside of the country before they've been released in mainland China. This has impacted theatrical releases outside of the region. For instance, Warner Bros. postponed the North American release of the Chinese-produced "Detective Chinatown 3" last month "in accordance with our partner's wishes and based on the current situation in China," a studio spokesperson said in a statement.

It's unknown how long China's theaters could be closed or how the canceled movies will be rescheduled.
