Taylor Swift scared 'Exorcist' sequel producer into moving horror film release date

'The one thing that scares me to death is Taylor Swift!' horror producer Jason Blum joked

Horror producer Jason Blum may be ready to take on demons, but he feels he is no match for Taylor Swift. 

The film veteran and founder of Blumhouse, who has produced hits like "Insidious" and "The Purge," said he made the decision to move the release of his latest film "Exorcist: Believer" up from Friday, Oct. 13 – a coveted date for a scary movie – after the "Cruel Summer" singer announced in August that the concert film of her "Eras" tour would open that day. 

"We had this amazing Friday the 13th in October, which is the single best day to release a scary movie," he told Entertainment Tonight. "Obviously, we moved off that and we bowed our head to Taylor Swift," Blum said of the new "Exorcist: Believer" Oct. 6 release date. "It was too risky to see if 'Exorswift' was going to take or not. People will still have the ‘Exorswift’ opportunity, so maybe we got to have our cake and eat it too."

When the "Style" singer made the surprise announcement in August that "Taylor Swift: The Eras Tour" would premiere in theaters on Oct. 13, Blum immediately suggested a "Barbieheimer" – seeing both "Barbie" and "Oppenheimer" – type of theatergoing experience with "Exorswift" on his social media, but he quickly decided he didn’t want to compete against the musical icon in his opening weekend.

Swift’s "Eras" tour has become a cultural phenomenon that not only sold out shows over the last year, but crashed Ticketmaster last year because of excessive demand for tickets.
