Doubleday starred opposite Michael Cera in the teen comedy Youth in Revolt (2009), based on the 1993 novel of the same name by C.D. Payne. Doubleday described her character as "mean" and "really complex" to the Los Angeles Times. She plays Sheeni Saunders, an imaginative girl with a dreary life who meets Nick Twisp (Michael Cera) while on a family vacation. The film, directed by Miguel Arteta, premiered at the 2009 Toronto International Film Festival.
