One of Angus Cloud's final roles before his passing in July 2023. Although production wasn't completed until months after his death due to the SAG-AFTRA strike, Cloud had filmed all of his scenes before production was shut down.

The abductors are given pseudonyms by the coordinator, Lambert, so that they don't know each other's real names in case one gets caught. These names are taken from The Rat Pack, the nickname given to a group of celebrities in the 1960s. They are Frank (Sinatra), Dean (Martin), Sammy (Davis Jr.), Peter (Lawford), Joey (Bishop) and (Don) Rickles. Comedian Don Rickles wasn't considered a fully-fledged member, but said "I never received an official membership card, but Frank made me feel part of the fun."
In an interview with Total Film, the directors felt they needed to apologize to the cast for the volume of blood they used on set. They said: "All of our movies are bloody. But I would say that this is definitely the most bloody. We spent a lot of time apologizing to our actors on this movie! I mean, blood is in the DNA of a vampire movie, and the amount of blood work in this one is... It's pretty extreme! But it's still fun."
Kevin Durand was able to change his character's origins and used his native Québécois accent, something he's never done on film before. When he pitched this to the directors, it was a no-brainer, and all the cast were able to help design the look of the characters, develop and alter their backstories. co-director Tyler Gillett even said: "of course, like why would you say no to that flavor? It makes it so interesting and so specific."
