What began with Kenny Powers rising like a Pheonix now gets a full-length trailer. Eastbound & Down officially returns to HBO on September 29. There’s curly blond hair, some car bashing, K.P. heading down a water slide, and a robot doing the robot (well, what else do they do?). Most important, we get a quick peek of Ken Marino, but there’s no sign of Lindsay Lohan. We’ll be here waiting for that promo.
