My Best Friend's Exorcism is a 2022 horror comedy directed by Damon Thomas (Killing Eve, Penny Dreadful), from a screenplay by Jenna Lamia and from the producers of other horror comedies Freaky and Happy Death Day. The film is based on the horror novel of the same name from author Grady Hendrix.
The year is 1988. High school sophomores Abby and Gretchen have been best friends since fourth grade. But after an evening of skinny-dipping goes disastrously wrong, Gretchen begins to act... different. She's moody. She's irritable. And bizarre incidents keep happening whenever she's nearby. Abby's investigation leads her to some startling discoveries--and by the time their story reaches its terrifying conclusion, the fate of Abby and Gretchen will be determined by a single question: Is their friendship powerful enough to beat the devil?
The cast includes Elsie Fisher, Amiah Miller, Rachel Ogechi Kanu, Cathy Ang, Clayton Royal Johnson, and Christopher Lowell.
