Behind the scenes
- In the films there is a portrait of someone called "Quintin Trimble". This may be a misspelling of Quentin Trimble, however, it is currently unknown if the two are to be taken as the same person or not.
"Trimble" may be a variation of tremble, to shake, which a person may do when confronted with dark forces, as he most likely did, given the literary work he authored.
