“I wanted her thoughts to be my thoughts,” Carson continues. “Her fears to be my fears. To love how she loved. To see the world through her eyes. In order to tell her story and to do Cassie justice, I needed to fully and completely dive into her skin, her heart and her mind.”

“Cassie and I are very different in a lot of ways, but in others, beautifully similar: Her tenacity. Her love of music. Her fearlessness,” Carson says. “Cassie is a force. And it was my honor to be her, and step into her skin, for a moment in time. I admire her deeply.”

“And I can’t wait for the world to meet her, so that they fall in love with her as much as I did,” she adds.

For Galitzine, he says he “felt compelled to immerse myself as much in the military culture as possible before taking on a role like” Luke.

“I think there’s such specificity that is required to play such a character so it was very much about understanding the process of creating a Marine — what basic training looked like, the intensity of it all, how they carry themselves, body language,” he adds.

To that end, “We spent an entire day atCamp Pendleton, which is one of the top military facilities in the country,” Galitzine tells PEOPLE. “I got to spend the whole day with real Marines, training, getting advice. It was such a memorable experience.”

He says, “I’ve taken away such an appreciation for the people who serve. The bravery it requires and the sacrifices someone is willing to make for their beliefs and for love.”

Carson says her chemistry with Galitzine “was instant, which is a vital part of telling a romance as deep and complex as ours.”

Adds Galitzine, “There were just a couple of really difficult scenes, very emotional scenes, that Sofia and I filmed together and I think just being able to go to that dark place with each other and support each other and feel the sort of closeness and the chemistry was super gratifying.”

“We truly were on this journey together,” Carson says. “We wholeheartedly committed to being Cassie and Luke and to telling their love story honestly and vulnerably. It was emotional, but we were there for each other.”
