Opposite Worlds is based on the hit Chilean format, Mundos Opuestos, originally broadcast on Canal 13 and distributed by Banijay International. In Opposite Worlds, 14 people from all walks of life go head-to-head in opposing teams that live in a house separated into two distinctly different worlds: one future and one past, each with its own unique advantages and disadvantages. Adding to the drama is a glass wall dividing the house into the two environments, allowing the teams to watch, envy and dread each other's every move. Viewers can contribute to the chatter about Opposite Worlds - and affect each weekly challenge - by following the handle @syfyoppworlds and using the hashtag #oppositeworlds on Twitter.
