It was a Swift exorcism of the movie theater.

Producers of the upcoming film “The Exorcist: Believer” announced on X (formerly Twitter) Thursday they will release the horror flick a week early to avoid competing with Taylor Swift’s “Eras” Tour film.

While both were scheduled to drop nationwide on Oct. 13, horror mega-producer Jason Blum decided to move up the film’s release to avoid any “Bad Blood” with Swift.

“Look what you made me do,” tweeted Blum, 54, referencing one of Swift’s hits. “The Exorcist: Believer moves to 10/6/23.”

The Post reached out to Blum and Swift, 33, for comment.

Swift managed to fill up the “Blank Space” of AMC marquees Thursday when she announced her concert film will open in cinemas across the US.

“The Eras Tour has been the most meaningful, electric experience of my life so far and I’m overjoyed to tell you that it’ll be coming to the big screen soon,” wrote the “Lavender Haze” singer on X.

Swift recommended fans embrace her “Style,” as “Eras attire, friendship bracelets, singing and dancing” will be “encouraged” at cinemas.

Per the film announcement, the 2-hour and 45-minute film will be played four times a day, on Thursdays, Fridays, Saturdays and Sundays, at every AMC location in the US.

Several online fans were quick to dub the second “Cruel Summer” lineup — of “Eras” and “The Exorcist” — as #Exorswift.

“Move over #Barbenheimer, here comes #Exorswift,” one fan wrote, referring to the summer’s “Barbie” and “Oppenheimer” double feature trend.

“I don’t know about you, but I feel like possessing youuuuuuuuuu,” a second fan quipped.

Other denizens of X were not so “Enchanted” by the pairing.

“I can’t wait to miss it,” snapped one enthused fan.

“Doesn’t matter, not gonna sit through another DGG disaster class whenever it’s released,” slammed another, referencing “Exorcist” filmmaker David Gordon Green.

“The Exorcist: Believer” stars Broadway’s Leslie Odom Jr. and Ellen Burstyn, who appeared in the original film.

The new one is set 50 years after the events of the 1973 movie.

Meanwhile, Swift’s tour — which started a bit off-key due to a Ticketmaster debacle — is projected to bring in a staggering $1 billion in ticket sales, which would make it the highest-grossing tour ever.

Ending its US “Love Story” in August, “Eras” is making its way to Argentina in November.

The US is not “Out of the Woods” yet — Swift is expected to return here in October 2024.
