NBC canceled the series after one season because Reynolds made such a fuss over forcing the network to honor their contractual obligation not to air cigarette ads during her show.
Reynolds' contract with NBC guaranteed a two season run, promised her a starring role in a feature film to be produced by the network and would also have given her partial ownership of a future series in which she needn't star. But the adverse publicity resultant from Reynolds' vociferous objections to a cigarette ad appearing on the initial broadcast caused that sponsor to withdraw their advertising from the network and eventually resulted in a lawsuit which gave NBC the right to revoke the guaranteed second season, cancel the proposed feature film and void the entire deal. Reynolds' career never fully recovered, and at one point she found herself homeless and literally living in her car.
The theme song and action in the opening credits were directly copied by Monty Python's Flying Circus (1969) in a parody called "The Attila the Hun Show" in the MPFC episode of the same name.
As an indication of how disinterested American audiences were in watching this show, it aired on NBC Tuesday nights, and was the lead-in for Julia, which drew a large enough tune-in to be considered a hit, while this was cancelled even before all 26 episodes had aired.
