A film adaptation of Camille Perri’s 2018 LGBTQ+ romance, When Katie Met Cassidy, is in the works at streaming service HBOMax, according to the Hollywood Reporter. Perri is set to write the screenplay; she previously wrote the 2016 novel, The Assistants, and worked as a books editor at Esquire and Cosmopolitan.

In the novel, Katie Daniels, a 20-something attorney in New York City, is getting over a breakup with a male art curator when she meets a woman named Cassidy Price, to whom she finds herself unexpectedly attracted. Kirkus called the book “a romance with a big heart and refreshing perspective”—although the reviewer also noted that it occasionally employs familiar rom-com tropes, such as “the opposites-attract scenario of commitment-prone romantic meets commitment-phobe realist.”

Ben Pugh is one of the upcoming film’s producers; he was an executive producer on the 2018 Netflix miniseries based on Richard Adams’ 1974 animal-adventure classic, Watership Down, and is producing a film adaptation of Majorie Wallace’s 1986 nonfiction book, The Silent Twins, currently in preproduction, with Black Panther’s Letitia Wright co-starring.

The When Katie Met Cassidy film is being produced by HBOMax’s WarnerMax division, a joint venture between the streaming service and the Warner Bros. movie studio. No casting news or prospective release date has been announced.

David Rapp is the senior Indie editor.
