High Quality Content by WIKIPEDIA articles! Detective Mark Hoffman is a fictional character in the Saw film series. 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. There are a few major differences however. Unlike Amanda, most of his traps give the victims the chance to escape. On the other hand, he has no emotion towards his victims, and in general, brandishes a very monotone personality.
