Jack Webb's last series, Project UFO, marked the end of an era, although, in truth, the series was a bit ahead of its time.
The syndicated documentary series, In Search Of..... might've been the inspiration for Webb trying one more procedural series, this time veering away from police work. Project UFO bowed on NBC in February 1978, airing on Thursdays, as I recall. A largely unknown cast carried the show for the first season, but when Project was renewed for a second year, Edward Winter (M*A*S*H) took over as the lead investigator. Unfortunately, viewers turned away to ABC's freshman comedy, Mork & Mindy. Enough said.
Frequent Webb collaborator Harold Jack Bloom created the series, and, along with Webb, wasn't heard from again after Project UFO ended.
