Alien Worlds was a science fiction/adventure omnibus—an anthology with the same characters set in the same universe, as opposed to an anthology of completely unrelated stories. The series was independently created, produced, and directed by Lee Hansen from 1979 to 1980. He produced 30 episodes covering 19 individual plotlines. Episodes were in standard 30-minute format, but story arcs were as long as 90 minutes.
It's the mid-21st century and the International Space Authority (ISA) is the body which governs space exploration and development. Alien Worlds follows the adventures of ISA staff as they encounter strange cosmic mysteries. Some episodes take place aboard Starlab, an orbiting space station, while other episodes take place throughout the galaxy. All of the episodes are full of action.
The series was written by Lee Hansen and Ron Thompson, with various co-writers, including Ken Ross, Jim Cook, Skip Press, Dudley Brown, Mike Hodel, and Babylon 5 writer J. Michael Stracynski. The full-symphonic soundtrack was written by Jim Kirk and performed by the London Symphony Orchestra.
