In addition to playing the demon and Bathsheba, Bishara is also the face behind the entity known as the "Lipstick-Face Demon" in both Insidious and Insidious: Chapter 3.
Oh, and that's still not all. Bishara composed the score for all of the aforementioned movies. In fact, his history as a composer is much more extensive compared to his history as an actor. Other composer credits include Annabelle, Dark Skies (which you can stream on Netflix), and V/H/S: Viral. In an interview with Film Music Magazine, Bishara explained how his dual roles as composer and actor intermingle. "It kind of combines for me in my head and in my body with the motions of the characters," he revealed. "It grows organically from things like posture and stance, motion will sometimes trigger a note array or rhythmic pattern or vice versa."
So, next time you see a scary demon in a movie, you'll know which name to check the credits for first.
Editor's Note: A previous version of this article stated that Joseph Bishara portrays the role of the demon nun in the film. The role is actually played by Bonnie Aarons. The mistake has been corrected.
