In 2010, Clarkson appeared opposite Leonardo DiCaprio in the Martin Scorsese-directed thriller "Shutter Island", playing a woman escaped from a psychiatric institution. Recounting being cast in the part, Clarkson said: "I got the call that every actor lives for. “Patty, Martin Scorsese is thinking of casting you in his new movie.” And I do what I call the little “Martin Scorsese dance” around my apartment. I think I was in my underwear or pajamas. It's a call you live for. Then I hear back, “But it’s just one scene.” So then I'm dancing a little lower. Then I hear, “It’s you and Leonardo DiCaprio in a cave,” and then I'm dancing again." The film was a box office hit, and Scorsese's highest-grossing film at the time.
