The Sci Fi Channel’s two newest offerings, Riverworld and The Phantom (based on the comic book and, as far as we can tell, completely different from the movie starring Billy Zane), have found their leads. For Riverworld, based on Philip Jose Farmer’s series of fantasy novels, former Battlestar Galactica star Tahmoh Penikett and Smallville’s Laura Vandervoort will play the show’s leads, a war correspondent and his wife who both die and are resurrected on Riverworld, a mysterious world populated by everyone who has ever lived (and died) on Earth.
