According to a blog of one of the cast members, this movie was filmed sporadically over three months in the early summer of 2021. Due to the Covid pandemic, this film did not have any staged rehearsals. Several scenes in the movie were intended as rehearsal shoots, only to be used in the film due to Covid-precautions, weather, location or budgetary issues making reshoots not feasible.
The director, to get everyone in character and as a Covid precaution, had everyone camp on site in rural Wisconsin for the first week of filming for the scene by the fire that parodies Red Dawn. All of the actors received tents, air mattresses and camped on site to get "into character" of three people traveling the countryside during a blackout with no electricity. The first night they camped, after hearing strange noises, an ATV with a 60 year old man roared into camp, scaring the hell out of everyone.
The blog mentions several other issues that the film experienced.
During the second week of filming, an actor Kyle Iverson, on his first day of filming, learned his mother was in the hospital, and exited the production before filming started that day, forcing the film to find a replacement within hours due to limited availability of the location in rural Illinois.
In addition, technical issues with a gimbal caused many planned shots to be done handheld with a Blackmagic Ursa Cinema Camera. These issues caused scenes in the first twenty minutes of this movie to be rushed, as a result of only having the ability to film in that location for a few days.
Two other actors later on were no-shows on their day of filming due to deaths in their family, forcing the production to find replacements due to location availability.
One actor, originally casted for Dr. Jekyll and Mrs. Hyde, was flown in from Los Angeles but had brain fog issues due to a medical condition possibly related to longcovid and had to be re-casted.
The nuclear silo in the movie was once a real nuclear silo, turned museum, in South Dakota. Days after filming there, the actor Anthony Wrobleski noticed a strange object hovering in the sky above a gas station in South Dakota and wondered if it was a UFO/UAP. Since filming at the silo, the film's director has reported seeing possible tic-tac UAPs about a dozen times, all that appear to be shiny, metallic and that move erratically through the air for a few moments before vanishing. In one case, as described in his book Atlantis & Its Fate In The Postdiluvian World, he saw a traditional saucer shaped UFO as well.
