Angel Vargas, who plays the titular character, was slated to reprise his role in Killjoy 2: Deliverance from Evil (2002), but declined in favor of other projects. Trent Haaga was cast in the second movie instead, and reprised the role in the subsequent sequels (Killjoy 3 (2010), Killjoy Goes to Hell (2012), and Killjoy's Psycho Circus (2016)).
