Like Cinq Nuits Chez Freddy (2023), Jim Henson's Creature Shop provided the animatronics for the movie.
With a budget of $51 million, this marks the most expensive Blumhouse production to date, surpassing Cinq Nuits Chez Freddy (2023), which had a $20 million budget.
In the movie, withered Foxy is not fooled by the Freddy mask. This reflects the gameplay of the second game.
Skeet Ulrich said he was able to bring a lot of his own interpretation to his character, as Henry Emily has never been visibly represented in the Five Nights at Freddy's universe until this movie. He stated that one of his recommendations was to show the character as an "80's nerd" & giving him a hoop piercing on his eyebrow. Per Skeet Ulrich & Matthew Lillard, everyone loved the idea though it eventually got nixed by a higher-up.
