Showtime's "In the 20th Century" is a millennium-related strand of feature-length documentaries in which famous directors take on major subjects of their choosing. In the third of the six films, "Yesterday's Tomorrows," filmmaker Barry Levinson delves into what we, as Americans, thought the future would be as we traveled through the 20th century.
