The two Knives Out movies—Knives Out and Glass Onion: A Knives Out Mystery—are firmly in the tradition of Agatha Christie whodunits. Director Rian Johnson has shared how he has been inspired by the British crime writer, and how he is consciously trying to emulate her in changing style for each film.
"Something I love about Agatha Christie is how she never tread water creatively. I think there’s a misperception that her books use the same formula over and over, but fans know the opposite is true," Johnson tweeted earlier this year. "It wasn’t just settings or murder methods, she was constantly stretching the genre conceptually. Under the umbrella of the whodunnit she wrote spy thrillers, proto-slasher horrors, serial killer hunts, gothic romances, psychological character studies, glam travelogues."
He continued, "When I made Knives Out, that’s what excited me about the prospect of making more mysteries with Daniel as Benoit Blanc—to emulate Christie and have every film be like a whole new book, with its own tone, ambition, reason for being."
That being said, the two Knives Out films do share similarities: They both feature Daniel Craig as Detective Benoit Blanc, and neither are too gruesome in their murders. In fact, viewers who love the films may like the "cozy mystery" genre, where the violence occurs off-screen, and an amateur sleuth is the protagonist. Or, Knives Out fans may also love mysteries where there is an established detective (like Detective Blanc) who pops into new plots in each book.
