Florence Pugh is to star in and produce “The Midnight Library,” the long-awaited film adaptation of Matt Haig’s bestselling novel.

Studiocanal and Blueprint Pictures — who first optioned the book in 2020 — have also attached Garth Davis (“Lion”) to direct the feature, from a screenplay by Olivier-winning Laura Wade (“Rivals,” “The Riot Club”) and Olivier and Tony nominee Nick Payne (“We Live in Time,” “The Sense of an Ending”).

The film is set to go into pre-production this autumn, with shooting to commence at the start of 2027. Studiocanal is launching worldwide sales at the 2026 Cannes market and will release the film theatrically across their territories of the U.K., France, Germany, Italy, Poland, Benelux, Australia and New Zealand.

In “The Midnight Library,” Nora Seed finds herself in a library between life and death with the chance to experience all the potential lives she could have lived. The story serves as allegorical exploration of mental health, focusing on depression, suicide and regret.

First published by Canongate Books in 2020, the novel has sold 15 million copies worldwide and has been translated into 56 languages. The audiobook is read by Oscar-nominated actress Carey Mulligan.

Graham Broadbent and Pete Czernin of Blueprint Pictures will produce the film with Anita Overland and Pugh. Blueprint’s Ben Knight and Diarmuid McKeown executive produce. Anna Marsh, Ron Halpern and Dan MacRae executive produce for Studiocanal. Haig also serves as executive producer.

“I couldn’t be more excited to reunite with Florence Pugh on ‘The Midnight Library,’” said Davis, who directed Pugh in the upcoming Netflix series “East of Eden,” based on the John Steinbeck novel. “Her warmth and talent are magical, and together I know we’ll do something special working with Matt’s iconic novel. This is a story that moves us both — a celebration of life in all its possibility and complexity. With Graham Broadbent, Blueprint Pictures and Studiocanal behind us, I can’t wait to illuminate this adventure.”

Added Haig: “I am so happy that Nora’s story is in such great hands, and that her myriad possibilities will be vividly reawakened by the absolute perfect team. And I can’t wait for people to see my book reimagined for the big screen.”
