Is Glass Onion Based on a Book?

“Glass Onion”, and its previous entry “Knives Out”, are not exactly based on any one book or author — but their inspirations can be found below.

Knives Out

You can read more about Knives Out here if you’re interested, but the TL;DR (Too Long; Didn’t Read) of that film is this: Knives Out was heavily inspired by Agatha Christie books like “Murder on the Orient Express” and “Ten Little Indians” — with the character of Benoit Blanc being a homage to Hercule Poirot

Glass Onion

Continuing with the running theme, “Glass Onion” only takes loose inspiration from Christie’s novels such as “And Then There Were None” & “Evil Under the Sun” — which also featured people on an exotic island.

Another notable inspiration was the whodunnit “The Last of Sheila” film
