A24’s “Backrooms” movie is scary enough, but a FOX11 LA anchor’s not-suitable-for-work mistake could be…darker.

He thought the movie was titled “Backdoor.”

Anchor Bob DeCastro joked on the Friday morning show that he was looking up the movie and put in the mistaken title.

“That’s a whole different genre,” entertainment anchor Amanda Salas cheekily said. “Whole different movie.”

Salas tried to move on, but the anchors couldn’t help but laugh.

“The back door!” DeCastro joked, breaking into laughter again. The anchor tried to joke about the issue more, but an embarrassed co-anchor, Jennifer Lahmers, put her hand up to quiet him.

“Good morning,” she interrupted to tell interviewers as they shifted to the traffic report, “how are you?”

Lahmers posted the clip on Instagram.

“You can’t take this man anywhere,” she wrote.

Commenters had a field day with the mistake.

“@bobbydtv do you have a link to the screener?” KTLA journalist Andy Riesmeyer asked.

“I love how @jennlahmers is trying hide when she’s smack dab in the middle of it,” another person said.

“Love the new Backdoor movie,” a third joked.

“Backrooms” opened on Friday to rave reviews, garnering an 89% Rotten Tomatoes score from critics and 74% from its audience. The movie is outpacing expectations, on its way to an opening between $85 million and $88 million, according to Deadline.

The movie stars Chiwetel Ejiofor and Renate Reinsve and is directed by Kane Parsons,

A New York Post review said the movie is “a disquieting and smart new horror film” that “is the brainchild of 4chan and YouTube users.”

The movie is based on a web series that explored fears of getting caught in an endless loop of ever-changing rooms.
