Meet the Star-Studded Cast of Life Itself, aka This Is Us The Movie

The Bates Motel actress will play an important role in the upcoming tearjerker, given how much trailer time she gets. We don't have a lot of details on Cooke's role, but according to the trailer, she is a scarlet-haired rockstar who shares a close relationship with Mandy Patinkin's character. She may possibly be Will and Mary's daughter, given that the movie spans across multiple generations.
