Rachel Weisz is in talks to join Michael Fassbender in The Light Between Oceans.
The Oz The Great And Powerful actress would play the Irish hunk's onscreen wife in the adaptation of ML Stedman's best-selling novel about a lighthouse keeper and his wife, who take in a baby they find washed up on the shore in a boat with a dead man inside, according to the Hollywood Reporter.
Swedish actress Alicia Vikander had previously been linked to the film.
The drama is being directed by Derek Cianfrance, whose previous films include Blue Valentine and The Place Beyond The Pines.
Set in the years after the First World War, on a remote island in Australia, the story follows a lighthouse keeper and his wife who find a boat washed ashore with a dead man and a baby inside. When they decide to raise the child as their own, the consequences turn out to be devastating.
David Heyman, of Gravity and Harry Potter fame, will produce, and the film is said to be eyeing a location shoot in Australia.
