Trivia: In the Des Moines diner, there's a brief shot of an elderly cook with sunglasses and sideburns. This is a reference to The Book, where Elvis Presley had faked his death and was living anonymously as a fast food cook.
Trivia: Alongside Witchfinder Sergeant Shadwell's ad for assistance with combating the forces of darkness is another asking whether anyone has found Uncle Terry's broad-brimmed black hat and also making mention of a red and yellow scarf. This is a reference to Terry Pratchett and his style of dress. (00:20:10)
Suggested correction: But it is a satanic church so Crowley can step in it.
There is nothing in The Book or the film to suggest that the graveyard is part of a "satanic church."
The church is run by Satanic nuns who are orchestrating the entire plan to switch babies.
No, it is not. Crowley has to drive for a considerable distance from the church to the convent in order to deliver baby Adam to the satanic nuns. They have nothing to do with it.
