Niall Armstrong will play Charles, the main victim who has been tortured and held captive for multiple days. He will look weak, rough, and have a large build to make the antagonist seem more intimidating for capturing someone larger. Niall has experience in performing arts and a scruffy beard to portray a beaten character. Bradley Smith will play the main antagonist, a serial killer businessman who enjoys watching his victims suffer. He has schizophrenia and switches between a sadistic and ordinary personality. Bradley has a smaller, stockier build and past acting experience that makes him suitable for the role. His face and voice are not obviously menacing, making it surprising that he tortures and murders people.
