The Fantastic Journey: Vortex
NBC premieres The Fantastic Journey, a “sci-fi-lite” series featuring such Star Trek veterans as story editor D.C. Fontana and director Vincent McEveety, but dealing mainly with familiar concepts (the lost city of Atlantis, post-apocalyptic futures that look a lot like southern California, etc.). It lasts only ten episodes before it’s cancelled.
