This made me think about a book from the late 70s I look through from time to time.The American Vein: Directions and Directors in Television by Christopher Wicking and Tise Vahimagi evaluates the contributions to tv drama of the Fifties, Sixties, Seventies by such directors as Sydney Pollack, Robert Aldrich, Bob Rafelson, Steven Speilberg, Budd Boetticher, Don Siegel and many, many more.To be sure
