Brian Levant has reflected on Mork and Mindy and the cliffhanger ending that left fans in limbo after ABC refused to renew the show for Season 5, per io9:
We even tried to get a fifth season. So here was the scenario: [Kalnik], another alien, became Mork’s buddy, and then [Mork] finds out he’s there to kill Mork for some reason. And so, to fend off this threat, they revealed themselves to the public [as an alien and his wife], and ultimately they had to run away through time to hide from [Kalnik].
Reflecting on the series and its ‘failed promise’, the exec producer continued:
It was going to be a semi-educational show, where Mork and Mindy traveling through time would meet with historical figures. We actually did a photo shoot for that, of [Mork and Mindy] standing with Abe Lincoln and Benjamin Franklin.
They were never able to keep it going at the same level, with the same enthusiasm, with the same innocence. And kind of the story of the series, to me, really is continuing to try and recreate that freshness and inventiveness that you saw the first time, every time. And really, you can’t do that.
I’m a little ambivalent today about Mork. It had such incredible promise, and we didn’t always deliver on that promise. We tried hard, but it was a gimmick show. Like Bewitched. Or Gilligan, or The Munsters or The Addams Family, you know? My Favorite Martian lasted three years. Gilligan’s Island, three years. The Munsters? Two.
