Manhattan (9pm, WGN) - WGN debuts its second original series tonight. “Manhattan” tells the story behind the Manhattan Project, America’s mission to build the world’s first atomic bomb in Los Alamos, N.M., in the 1940s. It’s created by Sam Shaw (“Masters of Sex”), directed by Thomas Schlamme (“West Wing”) and stars John Benjamin Hickey (“The Big C”), so the pedigree is there. The 13-episode period drama begins at 9pm tonight but moves to 10pm in subsequent weeks.
