If we didn’t already know that Michael Fassbender and Alicia Vikander fell in love while filming their drama The Light Between Oceans, this exclusive behind-the-scenes clip from the romantic period drama puts a shining spotlight on their undeniable chemistry.

In the video — in which we see brief clips of Fassbender and Vikander improvising their dialogue, movements and obviously enjoying each other’s company — director Derek Cianfrance says that when he was casting the film, he hoped he’d find two actors who made you believe in their romance.

“When you’re casting a romance, you want it to fit,” he says. “Alicia and Michael ended up working together in such a beautiful way.”

Later in the clip, Vikander, 28, recalls a moment during filming when Fassbender, 39, encouraged her to suggest things for him to do in a scene, which led to him bursting into song.

“The first day, he was like, ‘Give me a new idea!’ ” Vikander says. “That is not many times I’ve had another actor say that, and I just spelled something out.”

The clip then cuts to the moment in question — a very sweet scene where Vikander is working in the kitchen grading cheese and she asks Fassbender to sing her a song. He complies and belts out with what sounds like an Irish folk song.

The movie, about a couple who decide to raise a baby they find adrift in a rowboat, will be available to own and stream on Digital HD, Blu-ray, DVD and On Demand on Jan. 24, 2017.
