Russell T. Davies was commissioned by the BBC to write a 6 part serial to fill the opened up slot in Children's BBC in late 1991, when Tony Robinson decided to take a break from "Maid Marian and her Merry Men" and Russell T. Davies penned the first episode of "Dark Season" originally titled "The Adventuresome Three".
Russell T. Davie's 2008 "Doctor Who" Christmas Special, "The Next Doctor", recycles elements of the "Behemoth" in the "CyberKing". In both "Dark Season" and "The Next Doctor", the lead female villains are tricked into enthronement and entrapment inside a monster of their own making, which they accept as their destiny, but this leads to their downfall.
The "Doctor Who" production team originally sought to cast Kate Winslet as River Song in the revived series, as Kate Winslet had worked with Russell T. Davies on "Dark Season". The part went to Alex Kingston.
"Dark Season" contained some similarity to "Doctor Who", which Russell T. Davies revived in 2005. Most notably, Marcie occupies a similar narrative space to The Doctor, with Reet and Thomas as her companions. Nevertheless, the broad structural similarity to "Doctor Who" has been categorically denied by Russell T. Davies as intentional. Davies has claimed that the only direct reference to so-called "classic" "Doctor Who" is a scene in which Reet uses a yo-yo to test gravity.
