American Psycho

American Psycho is a horror novel by American writer Bret Easton Ellis, published in 1991. The story is told in the first-person by Patrick Bateman, a wealthy, narcissistic, and vain Manhattan investment banker who lives a double life as a serial killer. Alison Kelly of The Observer notes that while "some countries [deem it] so potentially disturbing that it can only be sold shrink-wrapped", "critics rave about it" and "academics revel in its transgressive and postmodern qualities".

A film adaptation starring Christian Bale as Patrick Bateman was released in 2000 to generally positive reviews. Producers David Johnson and Jesse Singer developed a musical adaptation. The musical premiered at the Almeida Theatre, London in December 2013 before then transferring to Broadway. In 2023 a five-issue graphic novel version of the book was released, but it strays heavily from the story of the book.
