The Cast For "Glass Onion: A Knives Out Mystery" Is Stacked

Cline, who's best known for her work in "Outer Banks," plays Duke's girlfriend, Whiskey. Cline told The Cut in December that she did a lot of research into the type of people Duke and Whiskey are, explaining, "I went down a very deep, dark rabbit hole of Dan Bilzerian parties and YouTube bodybuilders, like, 'Okay, this is who she's dating.'" She added of her character's style and attitude, "She never quite made it out of 2016." But she warns that Whiskey shouldn't be overlooked in this complicated puzzle box. "The funny thing about Whiskey is she's playing her own games," she told the outlet. "She's observing everybody around her. She has a façade as well."
