At the time of its premiere, this was the lowest-rated TV series in history, according to Nielsen viewership ratings. It has since been unseated.
The show was canceled after only two episodes; the remaining 11 episodes were burned off by the end of the season.
Inspired by Robert Louis Stevenson's classic novel "Strange Case of Dr. Jekyll and Mr. Hyde" (1886).
The NBC affiliate in Milwaukee pre-empted the second episode for snowstorm coverage, so only the first episode aired in Milwaukee.
