Which Film Adaptations Exist Of Memoirs Of A Murderer?

Whenever I'm deep in a true-crime rabbit hole I get fascinated by the odd corners where fiction, confession and cinema meet — and one thing that surprised me is how rare it is to find straightforward feature films that are direct adaptations of an actual murderer’s published memoir. There are, however, several interesting categories worth separating out: films adapted from fictional ‘memoirs’ of killers (books written in the first person), films adapted from novels titled like a murderer’s memoir, movies that use a killer’s own writings or interviews as source material, and films that dramatize true-crime nonfiction (books about killers rather than by them).

If you want concrete titles to explore, here are the ones I turn to most. For the literal title route, there’s the South Korean thriller 'Memoir of a Murderer' (2017) — adapted from Kim Young-ha’s novel — which is a tightly wound fictional story about an aging ex-serial killer with memory issues. It reads and plays like a twisted personal chronicle even though it’s fiction. Next, check out films that are fictional first-person killers adapted to screen: 'The Killer Inside Me' (two adaptations, 1976 and 2010) and 'American Psycho' (2000) are both novels written from a murderer’s or killer-protagonist’s perspective and translated into movies that feel like dark, internal memoirs.

On the “uses the killer’s own words/interviews” side, feature films more often draw from interviews, court testimony, or investigative books that quote the perpetrator. 'Monster' (2003) dramatizes Aileen Wuornos’s life and leans on interviews and court-record material rather than a tidy published memoir. For documentary-style adaptations of the perpetrator’s own material, Netflix’s 'Conversations with a Killer: The Ted Bundy Tapes' (2019) is a direct use of Bundy’s recordings and gives that unsettling first-person feel that a memoir would. Finally, there are films about killers adapted from nonfiction treatments or journalistic books — for example, 'The Executioner’s Song' (HBO, 1982) dramatizes Norman Mailer’s huge nonfiction novel about Gary Gilmore; it’s not a murderer’s memoir, but it’s a nonfiction dramatization of a murderer’s life.

So if you’re after the feel of a murderer’s own memoir on screen, my go-to recommendations are to watch 'Memoir of a Murderer' (2017) for a novel-turned-film that plays like one, 'American Psycho'/'The Killer Inside Me' for fictional first-person killers, and the Bundy tapes documentary if you want the real voice captured directly. I love how each approach changes your sympathy and disgust — and which one creeps you out more will probably tell you a lot about what you like to watch at 2 a.m.
