Several episodes contain plot threads that link them together. For example, the "Innobotics arc" - the story of lifelike androids created by the Innobotics Corporation - runs through these episodes: Valerie 23, Mary 25, The Hunt, In Our Own Image, and Resurrection.
The SciFi Channel quietly took over co-production in 2001, after the series was cancelled by Showtime (Season 7). Apparently there were already some cable-ready episodes in the can at the time of cancellation, as the MA-rated "Flower Child" was only broadcast during the show's syndication-only run. On the whole the SciFi-MGM relationship resulted in lower-quality episodes and clip-shows. The SciFi Channel was still administrated by the Vivendi-Universal group at this time. An "unsanitized" version of "Flower Child" appears on DVD in the US release of the Outer Limits' "Sex and Science Fiction" collection.
Sam Egan, the writer of the award-winning 100th episode of the series, "Tribunal", based the story of the episode on his father's experience in Auschwitz during World War II where his first wife and their young daughter were murdered by the Nazis.
Film composer Howard Shore was hired to provide the new theme music to the series, however, when the producers heard his old fashioned orchestral theme, they decided they wanted to go with a more modern approach. John Van Tongeren heard Shore's theme and looked over it, as he was asked if he could add anything to Shore's theme. In the end a new modern theme was done by John Van Tongeren and Mark Mancina.
