Linda Blair says she came on 'Exorcist: Believer' to help the young actors, Lidya Jewitt and Olivia O’Neill Instagram Blair revealed that she was contacted by the producers to serve as a guardian to Lidya Jewitt and Olivia O'Neill due to her public outcry against child abuse, especially from her own experience. "I felt they should cast maybe a little older, and they said, 'No, we want to stay honoring sort of the Reagan legacy,' and I said, 'Well, if you do that, these are the things you need to put into place,' because I've gone on record saying, 'Don't ever do it to a child again; it was child abuse,'" she shared.

"Everybody really appreciated what I did for them; even the adults said that they took advantage and that they appreciated that I put certain things in place. And so when I did create this atmosphere for them, I kept an ear and an eye on everything. THE EXORCIST, Linda Blair, 1973. (c) Warner Bros./ Courtesy: Everett Collection.
