Sam Claflin is in negotiations to co-star with Rachel Weisz in Fox Searchlight’s “My Cousin Rachel,” an adaptation of the classic Daphne Du Maurier novel.

The dark romance revolves around Philip, played by Claflin, a young orphan, who believes his mysterious, beautiful cousin Rachel, played by Weisz, may have been responsible for the murder of his beloved guardian Ambrose, also a cousin of theirs. As Philip plots his revenge, his feelings become complicated as he falls under Rachel’s beguiling spell.

The book, originally published in 1951, was previously adapted into a film starring Olivia de Havilland and Richard Burton and directed by Henry Koster. This version will be helmed by Roger Michell, who will also adapt the script.

After breaking onto the scene opposite Johnny Depp in “Pirates of the Caribbean: On Stranger Tides,” Claflin gained notoriety when he landed the role of Finnick in “The Hunger Games” franchise, which quickly lead to more studios eyeing the thesp for more leading-man roles.

Besides “Hunger Games: Mockingjay – Part 2,” bowing this November, Clafflin also reprises his role in “The Huntsman” opposite Chris Hemsworth as well as starring opposite Emilia Clarke in MGM’s “Me Before You,” both of which bow in the summer frame.

Claflin is repped by CAA and Independent Talent Group.
