It was announced in Oct. 2021 that actor Peter Scolari, who played Father Thomas Marx, passed away after a two-year battle with cancer. Evil co-creator and showrunner Robert King wrote several tweets about the actor, calling him "one of the funniest--sneakily funny--actors we've worked with," he said. "He always took a nothing scene and found different ways to twist it, and throw in odd pauses that made it jump. I will try to collect my thoughts more. He was just wonderful."

There are subliminal puzzle pieces that are scattered in the show that flash in 1 frame. They are usually in a place where they don't pop out too much at the viewer-- like in the first frame of a shot, or in a brighter part of the frame. There are no puzzle pieces in the pilot. And the others contain somewhere between three and eight puzzle pieces. There is a line in the third where the exorcist character says... "We are fighting the worst enemy on earth, and their only vulnerability is they reveal themselves in symbols and numbers. They can't help it. God draws in straight lines. The devil draws in puzzles and anagrams."
