Duff stars in film Stay Cool with costars Winona Ryder, Mark Polish and Jon Cryer. The movie follows author Henry—played by Polish—who reunites with an old high school flame Scarlett—played by Ryder—in his hometown to give a commencement speech. Duff’s character Shasta O’Neil tries to weasel her way into Henry’s love life by inviting him to her prom.
She (Shasta) is a very normal girl. She is a high school student graduating, but she is really spunky and kind of larger than life and she’s a huge flirt. That’s not really me in real life so it was fun to get to do.
