Episodes of the TV series included In the Mouth of Darkness, The Horror from the Blizzard and Nightshade and the Imps. (AUDIO: Nightshade) Emile Mars-Smith had a Professor Nightshade action figure. (PROSE: Deadfall) The Eighth Doctor was a fan of the series, judging by the fact that he once told Dave Young that he had "never really rated TV science fiction since they got rid of Nightshade." (PROSE: Escape Velocity) Sacker compared the escapades of Jago and Litefoot to an episode of this series, "only far less plausible". (AUDIO: The Final Act)
