Rian Johnson's Knives Out sequel finally has a mysterious title
Johnson's next caper has many crystalline layers to it

In Rian Johnson’s whodunnit Knives Out, a metaphorical donut and donut hole lay out the mystery. For the film’s sequel, another food will guide the way: The multilayered onion. That’s right, the title for Benoit Blanc’s next adventure is Glass Onion: A Knives Out Mystery.
The film is slated to drop this fall and ahead of the release, Johnson once again explains the everlasting influence of Agatha Christie on his work—and the title.
“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 writes in an announcement on Twitter.
“It wasn’t just settings or murder methods, she was constantly stretching the genre conceptually,” Johnson continues. “Under the umbrella of the whodunnit she wrote spy thrillers, proto-slasher horrors, serial killer hunts, gothic romances, psychological character studies, glam travelogues.”
