Zombie extras were recruited from "Spaced" fan communities. Wright said in 2020 that " zombies spent a week cooped up on set. They had to stand outside The Winchester, the pub where our heroes take refuge, banging on the windows and not doing much else really. When we eventually involved them properly, they had this electric energy: a pure, crazed hysteria". Originally, there were 40 stunt performers hired to be the zombies, but the production realised that they would need a lot more to fill the set pieces. So many fans responded to the online call that auditions to select zombies were set up. There were 150 zombie extras until local children saw the zombie make-up and wanted to be involved, leading to another 50 child zombies being added.
