Within a few months of its abrupt cancellation, several of the show's production team would be producing the thematically similar Logan's Run for the Fall 1977 season.
Although airing in a time when the nation's interest in the Bermuda Triangle, UFOs and fantasy was at a height, the show failed to last beyond the ten episodes, having been scheduled as a mid-season replacement (following the failure of another fantasy series, Gemini Man) against The Waltons and Welcome Back, Kotter, both very popular family shows. NBC ordered 12 episodes to follow the revised pilot, but production ended early when it was apparent that the ratings were low. The show was either pre-empted or its time-slot changed several times during its short run. By its tenth episode, its ratings had dropped, and it was cancelled.
The Fantastic Journey (1977) used sound effects from Star Trek (TV Series 1966-1969) in a few of its episodes.
Opening narration: "Lost in the Devil's Triangle, trapped in a dimension with beings from the future and from other worlds, a party of adventurers journeys through zones of time back to their own time. Varian, a man from the 23rd century, possessing awesome powers. From 1977, Fred, a young doctor just out of medical school. Scott Jordan, the 13-year-old son of a famous scientist. Liana, daughter of an Atlantean father and an extraterrestrial mother. And Jonathan Willaway, rebel scientist from the 1960s. Together they face the frightening unknown on...the fantastic journey."
The show benefited from a larger than normal amount of location filming, with familiar sites such as the Hollywood Hills, Zuma Beach, the Bonaventure Hotel in LA and Griffith Park Observatory all appearing in various episodes.
The script for an unproduced eleventh episode, "Romulus", circulates on the Internet.
