“Showdown At The Grand” (* out of four) was a cut-rate action schlockfest about an independent movie theater owner (Terrance Howard) who teams up with a former action star (Dolph Lundgren) to defend his theater again ruthless killer corporate developers (John Savage, Amanda Righetti, and others) resulting in a showdown to the death. Witless and artless homage to grindhouse cinema gets more dreadful by the minute. Lundgren (in a terrible wig) sleepwalks his way through another laughable performance and Howard can play this role in his sleep by now. Film is hardly a “grand” slam for either of their careers.
