A man yelled “Allahu Akbar” during a Paris screening of the box office hit “Joker” — in an apparent attempt to steal panicked theater-goers’ belongings, according to new reports.

The unidentified 34-year-old suspect started mumbling, “It’s political,” several times from his seat midway through the 9:30 p.m. screening of the blockbuster at the Grand Rex cinema in Paris, Le Parisien reported.

At first, other viewers laughed it off, but then shushed him, according to the report.

That prompted the man to yell the Arabic phrase, which translates to “God is great.”

About 25 audience members in the theater — which can accommodate 500 but held about 200 that night — made a beeline for the exits, but the doors were blocked, according to the report, which did not elaborate on the obstruction.

The rest stayed behind and continued watching the flick — but the entire theater was ultimately evacuated as authorities brought in the bomb squad and dogs.

“It was total panic,” a viewer named Victor told Le Parisien. “People jumped over seats and women fell to the ground in the aisles.”

The suspect was arrested, but was subsequently admitted to a psychiatric infirmary within police headquarters.

The director of the Grand Rex told The Hollywood Reporter that the suspect didn’t act alone.

“They were two thieves looking for a way to take people’s phones and bags. Apparently, they had already used the same tactic once on a train,” he told the outlet.

In the US, authorities nationwide — including the US Army and the NYPD — issued warnings of possible “incel” violence inspired by Joaquin Phoenix’s murderous clown character.
