Journey to the Far Side of the Sun (DVD)

A space-race develops when a new planet is discovered on the far side of the sun, in this Gerry and Sylvia Anderson-created, effects-driven, sci-fi tale with a twist. When a new, previously unseen planet is discovered on the opposite side of the sun, 100 years in the future, a European space agency hurriedly dispatches a spaceship to investigate. But when astronauts Col. Glenn Ross (Roy Thinnes) and John Kane (Ian Hendry) are forced to crash-land, their dazed condition leads them to believe they're back on earth. It's not long, however, until they both discover the shocking truth: the undiscovered planet is actually a doppelganger of the earth, similar in every respect, but a mirror-image.
