Kate Winslet and Saoirse Ronan are on their way to falling in love.

The acclaimed actresses are set to star in the period romantic drama "Ammonite" from "God’s Own Country" writer-director Francis Lee, according to Deadline.

The movie, set in a British coastal town in the 1820s, follows the unlikely romance between fossil hunter Mary Anning and a London woman of means to whom she must unexpectedly play nursemaid.

The real-life Anning is credited with making key scientific discoveries in the Jurassic marine fossil beds in the cliffs along the English Channel. However, at the times, she was not recognized for her work as she was a woman.

Lee previously made "God’s Own Country," about the homosexual romance between two young farmhands, which was a Sundance darling and a critical hit and a box office breakout in the U.K.

Ronan can currently be seen in "Mary Queen of Scots," while Winslet most recently starred in last year's "Wonder Wheel" and is currently filming "Avatar 2."
