Jason Blum moves 'The Exorcist: Believer' premiere date to avoid competing with Taylor Swift's Eras Tour film

• Taylor Swift announced the Eras Tour concert film will premiere in theaters on October 13.
• "The Exorcist: Believer" was originally scheduled to premiere the same day.

Taylor Swift shocked fans and Hollywood execs on Thursday by announcing her new concert film.

Swif's blockbuster Eras Tour will come to the big screen on October 13, which is famously her lucky number. Within hours, there were reports of queueing and glitches for Swifties attempting to buy tickets, even though AMC said it "bolstered its ticket server capacity" in preparation.

"No ticketing system in history seems to have been able to accommodate the soaring demand from Taylor Swift fans when tickets are first placed on sale," the company said in a statement.

"The Exorcist: Believer," the sixth installment of the franchise, was originally scheduled to be released on the same day, inspiring memes online about an "Exorswift" double feature.

But it looks like horror fans will be treated to an early premiere instead. Jason Blum, founder and CEO of Blumhouse, tweeted that "The Exorcist: Believer" will be moved up to October 6, presumably to avoid competing with Swift at the box office.

Blum announced the news by quoting one of Swift's songs: "Look what you made me do." He also added the hashtag "Taylor Wins."

Representatives for Blumhouse did not immediately respond to Insider's request for comment.
