In The Light Between Oceans, fate has dealt Tom (Michael Fassbender) and Isabel (Alicia Vikander) an awfully tricky hand. The happy couple live off the coast tending a remote lighthouse, and they’d like nothing more than to bring a baby into their lives. But after Isabel miscarries, a loaded miracle soon arrives in the surf: an abandoned, crying child, which Isabel is insistent they take in and raise as their own. For years, all is well, until Tom and Isabel meet a widower (Rachel Weisz) who lost both her husband and child at sea … and as it becomes clear that the woman’s long-lost daughter is the same child Tom and Isabel have adopted, their family’s lashed-together union threatens to fall apart. What should they do? What would you do? Directed by Blue Valentine’s Derek Cianfrance, The Light Between Oceans comes out on September 2, but you can get an exclusive, minute-long special look at the film below.
