Visible crew/equipment: A mic boom operator is visible on the left hand side of the screen wearing a white t-shirt, beige shorts, and sneakers. He's carrying the boom mic and following Mulder and Scully. You can see him when Mulder and Scully arrive at the "Church of God with Signs and Wonders" for the first time...when Mulder delivers the line "That's funny, I knew a couple Catholic schoolgirls who were experts at it."

Factual error: When Reverend O'Connor is reading from the Book of Revelations, his Bible is flipped open towards the front. Revelations is the last chapter in the New Testament, so his Bible should have been open towards the back.
