Trivia: The directorial debut of series co-star Patrick Wilson.
Trivia: Nicolas Cage is well-known for turning down roles if he doesn't play the lead character. However, he agreed to do this film as he's always wanted to play Count Dracula, even though Nicholas Hoult is the lead character.
Trivia: Peter Dinklage plays Toxie's human form Winston and also recorded all the character's dialogue as the "Toxic Avenger." But Toxie, in his final "Toxic Avenger" form, is physically played by a woman named Luisa Guerreiro under heavy makeup, as Dinklage was very uncomfortable with the excessive prosthetics. Guerreiro and Dinklage worked closely together to create the physical mannerisms of Toxie so their performances would match, and so Guerreiro could more naturally lip-sync Dinklage's dialogue.
Trivia: The filmmakers wanted to honor the fact that the villains are animatronic robots and decided to use practical effects instead of CGI. The Jim Henson Creature Shop actually built fully-functional animatronic puppets for each character, in addition to suits that could be worn by actors for movements that were too complex for the animatronics to do.
Trivia: A teacher at a Miami charter school showed this film to his 4th-grade class. He allowed them to select the film they wanted to watch, and they picked this, with nobody realising it was a horror film. Apparently, the movie played for over 20 minutes before the teacher shut it off, despite earlier protests from his students about its content.
Trivia: The "Prime Video" includes a goof/factual error stating: "At 18:26 when Ben looks in the refrigerator there is definitely light illuminating the interior despite there supposedly being no electricity in the house. In addition, he sets his flashlight on the table so it can't be from that." To the contrary, there is no apparent power outage. Jack leaves Ben a note stating "Keep lights off. Stay hidden" and Ben later flicks off the light switch. The reported "factual error" is nonfactual. (00:04:35 - 00:12:07)
Trivia: Mary is chained outside in the cold and asks Father Munhauser if she can come inside. Father Munhauser replies, "I'll let you sleep in the attic if you can recite for me 'Leviticus Chapter 3'", which she cannot. Leviticus Chapter 3, probably most commonly known as the "Peace Offering," is about 500 words long. (00:01:35)
Trivia: Neil (thief) sees the rag doll on the chair and says, "Holy Smokes, this is old." The "Raggedy Ann" doll begins as a book character in "Raggedy Ann Stories" (1918), but is created three years earlier by cartoonist Johnny Gruelle. Raggedy Ann and brother Raggedy Andy dolls are still manufactured today. The Raggedy Ann doll in the movie appears to be circa 1940s and might sell for $100 - 200 (used) on E-Bay. Dolls imprint with the 9/07/15 patent date may worth $1,000 - 3,000. (00:35:20)
