Based on an idea by Bob Odenkirk, who dealt with a home invasion himself by trapping the trespassers in the basement. He was frustrated with how the authorities dealt with the situation and had thought about how he would take the matter into his own hands if he "was a badass."
Bob Odenkirk does almost all of his own stunts, and fight scenes use long cuts to show that it is him doing the moves and not a double.
Bob Odenkirk's physical training lasted two years in the lead-up to making this film and he recalls sharing his intentions with an actor (whom he likes but won't name) only to have the man reply "Why are you training? They have guys who do the fighting for you." He's understandably proud of his work here adding that "I had so much fun doing the fight sequences."
Bob Odenkirk himself has had two break-ins occur at his own home, "one of which was extremely traumatic for my family." He had his own complicated and difficult feelings on the subject and brought those into the conversation regarding the shaping of this story and character. "You always wish you'd done more."
The story originally started with the break-in, but they added the opening montage early on to help set Hutch as a man feeling trapped in the mundane cycle of suburban family life.
