Linda Blair reveals if she will be in ‘Exorcist’ reboot: ‘Everybody is up in arms’

“I’m just getting texts from everybody,” she exclusively told The Post after it was announced that Ellen Burstyn would reprise her 1973 “Exorcist” role of Chris MacNeil — mother of devil-possessed teen Regan MacNeil, played by Blair — for an upcoming $400 million sequel trilogy to the classic horror film.  However, one key casting question was not addressed by the announcement: Will Linda Blair reprise her own character for the project?
