Sept. 24 (UPI) — Chinese pre-release viewers of an Australian movie saw a straight couple’s wedding when it should have been two men getting married.

The horror film, Together, starring Dave Franco and Allison Brie, was altered seemingly by using artificial intelligence before it was shown in China.

In a scene with a wedding between two men, one of the men’s faces was altered to be a woman’s, purportedly using AI, Out reported. The scene reveals plot points in the movie, which means the change created confusion for viewers.

Viewers in China only noticed the change when they saw side-by-side screenshots on social media, The Guardian reported. “What’s happening outside the film is even more terrifying than what’s shown in it,” wrote one Weibo user. Weibo is a Chinese social media site.

It’s not unusual for western movies to undergo Chinese censorship before being shown there. Often, the censorship is performed via cut scenes. But the use of AI or other technology to change the scenes is new, The Guardian said.

The film was scheduled to be released in China on Sept. 19, but after the outcry about the change, the film’s Chinese distributor has pulled the film, citing “changes in the film’s distribution plan.”

Homosexuality is no longer a crime in China, but it still faces strong stigma. The government had a longstanding stance to neither support or oppose LGBTQ+ relationships, but that has changed in recent years with a crackdown on gay groups.

In 2016, China’s censors banned “abnormal sexual behavior,” among other things the government disapproves of, in films and TV.

One RedNote user said that the use of AI to gender-swap gay characters was “humiliating minority groups.” Public opinion of homosexuality is on the rise in China.
