Ed Norton takes a note from likes of Michael Cera (Youth in Revolt) and Sam Rockwell (Moon) in his new film, Leaves of Grass, playing the opposites side of the same coin — Billy, the academic, and his brother Brady, the stoner. The film, directed by Tim Blake Nelson, surrounds the Kincaid twins (again, both played by Norton) and the dark shenanigans that ensue when the hippie half tricks the other into returning to their small hometown of Oklahoma. If you’re a fan of Norton, Grass may be the perfect drug. The film is very much character-driven, and delivers two different helpings of Norton flavor. Beyond the stimulating textures of Billy and Brady, however, the plot is mostly mellow with occasional hits of complexity and violence.
