Why does the second season of SPACE:1999 look so different from the first? The series was completely revamped to appeal more strongly to the U.S. market after a disastrous first season in the U.K. on ITV. STAR TREK third season producer Fred Freiberger was brought in and made sweeping changes: Most of the cast was let go (by mid-season, only Martin Landau, Barbara Bain, and Nick Tate remained of the original cast), new cast members added (Tony Anholt and Catherine Schell being the most notable), and sets and costumes completely redone. Despite the changes, the show declined steadily in the all-important U.S. ratings and was not renewed for a third season.
