“The Wackness” – In “The Wackness,” Luke (Josh Peck) is a recent high school graduate who sees dealing weed as a solid summer job. A bit of a loner he strikes up a friendship with his therapist (Sir Ben Kingsley), who he pays in weed. Method Man plays Luke’s supplier. Olivia Thirlby plays the therapist’s daughter who becomes involved with Luke. In “The Wackness,” one of the walking dead, Mary Kate Olson, plays one of Lukes ‘clients’ – a dread-headed stoner.
