Here's the first trailer for Jeremy Piven's upcoming British series Mr. Selfridge, about Harry Gordon Selfridge, the American who founded the fancy schmancy U.K. department store Selfridges in 1909. Our immediate take: One, Piven's mustache is distractingly fuller than his beard. Two, "Sing, Sing, Sing" came out in 1936. And three, hey, old-fashioned shopping! It's so glamorous!
