Trivia: The Time Tunnel
- Channel Hop: It had an insane case of this in Britain; The BBC showed 13 episodes in 1968 (not the first thirteen, mind you), with the series transferring to ITV in 1970 - it took the regions that showed it until 1974 to get through the whole run (and even then, they seem to have skipped "Idol Of Death"); they had another chance in the very late '80s. Thanks to other channels, the entire series did eventually get UK airings.
- Prop Recycling: Irwin Allen reused many of his futuristic props and costumes from Voyage to the Bottom of the Sea and Lost in Space in episodes such as "Visitors From Beyond the Stars." Props created for The Time Tunnel were reused on those series (and Land of the Giants) as well.
- Screwed by the Network: Fans have competing theories on The Time Tunnel's sudden cancellation, and none of them reflect well on ABC. Some people contend that the show was sacrificed to make room for Custer, a short-lived Western about the famous soldier that was as ill-fated as its subject. Martin Grams' The Time Tunnel: A History of the Television Program suggests that a new regime wanted to get rid of their predecessors' projects. One thing is certain, though: ABC didn't do the series any favors by pitting it against The Man from U.N.C.L.E. on NBC and The Wild Wild West on CBS.
