“Waves” stars Kelvin Harrison Jr. and Alexa Demie faced a few challenges while playing their lead roles of Trey Edward Shults’ drama, but the duo spent a lot of time together to balance it out.

“There were quite a few challenges in playing my part,” Demie told TheWrap’s Steve Pond at the Toronto International Film Festival. “It was a lot of high, chaotic emotion and just bringing that out takes a lot out of you, but the good thing was, Kelvin and I spent a lot of time together and when we weren’t filming those hectic scenes, [we’d] try to have fun and go to the beach and enjoy ourselves. With every great thing comes challenges, and I think we all had our challenges but it was worth it.”
