Syfy says it is planning a U.S. version of the Chilean reality competition series \"Opposite Worlds.\" The American cable television network said it has acquired the exclusive U.S. format rights from Canal 13 and distributor Banijay International. \"Opposite Worlds\" will consist of 12 episodes to air over six weeks. \"\'Opposite Worlds\' has become an absolute phenomenon. This groundbreaking, edgy program is a remarkable television experiment transporting the audience and the contestants into starkly opposite worlds, simultaneously. This will be a terrific addition to our prime-time schedule which will fascinate Syfy viewers and invite them to play a part in the action and outcome,\" Mark Stern, president of original content for Syfy, and co-head of original content for Universal Cable Productions, said in a statement Monday. In the show, 20 people from all walks of life are mixed together in two opposing teams that live in two distinctly different worlds -- the past and the future. \"The future is a utopia where every wish can be granted with a push of a button; the past is a constant struggle for survival,\" a synopsis said. \"Each week, players compete in a series of challenges to determine who lives in the past and who lives in the future.\"
