Detective Lieutenant Mark Hoffman is a fictional character from the Saw franchise. He is portrayed by Australian actor Costas Mandylor. While the character was first shown as a police officer in Saw III, later films in the series have expanded his role and revealed him to be an apprentice, and subsequently the successor of the Jigsaw Killer. Like his mentor and partner, he designs death traps that, for survivors, give them reason to appreciate their lives. Unlike his mentor, however, he has no emotion towards his victims and generally displays a very monotone personality.
