Stone took on the role of a clinically depressed woman in the independent drama "When a Man Falls in the Forest" (2007), premiered in competition at the 2007 Berlin Film Festival where it was nominated for the Golden Bear. She found her part "challenging" to play, remarking: "It was a watershed experience. I think that we live in a [...] Prozac society where we're always told we're supposed to have this kind of equilibrium of emotion. We have all these assignments about how we're supposed to feel about something." Her next film roles have been in independent productions, including the late 2000s films "If I Had Known I Was a Genius" (2007), "The Year of Getting to Know Us" (2008), "Five Dollars a Day" (2009) and "Streets of Blood" (2009), all of which were direct-to-DVD releases in North America.
