Ineson is known for his signature baritone voice, which lends itself perfectly to an evil demonic force that the characters of the film will face. Many may remember Ineson for his roles in iconic films, such as both parts of Harry Potter and the Deathly Hallows and The Witch by director Robert Eggers, where he played William, the father figure of the film's central family.

Most recently, he starred in several prominent films, such as The Green Knight, where he played the titular character, alongside minor roles in The Tragedy of Macbeth and The Northman, another movie by Eggers. Alongside his role as the demonic entity in The Pope's Exorcist, Ineson is also set to star in True Love, a science fiction flick from Rogue One director Gareth Edwards, and Misanthrope​​​​​​​, an upcoming thriller by Damián Szifron.

The Pope's Exorcist will be released on April 7.
