One of her first big breakout roles was playing one of the lead characters in the short-lived WB 2001 sitcom "Raising Dad." That same year, she made her feature film debut in the hydroplane racing movie "Madison." In 2006, though, Larson landed her first leading role in Will Shriner's 2006 activism drama "Hoot," based on the novel by Carl Hiaasen. The movie starts from the perspective of Roy, played by Logan Lerman, who stumbles into construction sabotage efforts by the handsome and athletic Napoleon (Cody Linley). Beatrice and Napoleon, it turns out, are step-siblings, and the three combine their efforts to stymie construction and protect the owls.
