Adi Peichl and Peter Wetzelsberger were extras for Narcissus and Goldmund (2020) by Stefan Ruzowitzky, playing monks. Peichl, actually a very nice guy, told his colleague monks about the time he had to play a rapist on stage and he described the experience in all its shocking details. Seeking the cast for Animal Control one year later, he was naturally the first choice for the role of Ferdinand.
The font used for Animal Control is "Bourbon Grotesque" by Jeremy Vessey.
The "testicles" in the jars were actually Rambutan, a tropical fruit similar to Lychees.
Some of the bruises on Adi Peichl's body were real and indeed a result of the more brutal scenes filmed at the Bus station, the evening before.
