AMC's released a second teaser for "Turn," its upcoming Revolutionary War drama starring Jamie Bell as a spy working against the British. The series was created by Craig Silverstein ("Nikita"), with Rupert Wyatt ("The Escapist") directing the pilot episode. No premiere date has been announced for the series yet, but it's one of two new dramas AMC will be debuting next year -- the other, "Halt & Catch Fire," is set in the tech world of the '80s.
