Liane Moriarty’s film adaptation The man’s secret has found its director, Deadline reports

Kat Coiro has reportedly agreed to direct the adaptation. She is known for her work in TV shows including: It’s always sunny in Philadelphiadead to meand girls5eva, as well as the new movie Marry me

Moriarty’s novel, published in 2013 by Amy Einhorn/Putnam, follows a woman who finds a letter from her husband that he wanted her to read after his death. She reads it while he’s still alive, and discovers he’s been keeping a shocking secret.

In a starred review, a critic of Kirkus wrote of the book: “There is real darkness here, but it is offset by the author’s natural humor – she weaves in Pandora myth and a history of the Berlin Wall – and unstoppable goodwill towards her characters.”

Christy Hall (I’m not okay with this) is writing the screenplay for the film, which will be produced by Paul Weitz, Chris Weitz and Andrew Miano of Depth of Field, the production company behind such films as about a boya single manand Nick & Norah’s Infinite Playlist

Moriarty’s books have proved popular fodder for film adaptations. her novels big little lies and Nine Perfect Strangers were both adapted into television series, and last week it was announced that: Apples never fall will form the basis of a show for NBC’s streaming service Peacock.
