Evidently, this episode of Bewitched was scripted by Lila Garrett and Bernie Kahn before the "birth" of Samantha's son Adam, but not filmed until afterward; as a result, the action is framed in the form of a flashback. Darrin recalls how he was cloned by Endora so that he could spend time with his pregnant wife Samantha while simultaneously attending a business conference in Japan. Richard Loo, the "heavy" in many a World War II propaganda film, is here cast as Mr. Tanaka. "Samantha's Better Halves" first aired on January 1, 1970. ~ Hal Erickson, Rovi
