Father Gordon's arrival to the Glatzel house is, as Chaves said, "without a doubt, a shameless Exorcist reference." It almost perfectly replicates the arrival of Father Merrin from the 1973 film, albeit The Conjuring 3's Father Gordon fares a tad bit better in his dealings with a demonic entity. Other scenes that seemingly draw inspiration from The Exorcist involve David Glatzel's demon contortions mid-exorcism, which are reminiscent of Reagan's spider walk, and Arne Cheyenne Johnson's levitation in the final moments of his eventual exorcism.
