The first episode of a vastly retooled Battlestar Galactica (or, depending on how you look at it, the first episode of the show’s second season) premieres on ABC, with an almost completely new cast. Kent McCord, Robin Douglass and Barry Van Dyke take over as the series leads; the only holdovers from the original season are Lorne Greene as Adama and Herb Jefferson as Boomer.
