I thought this would be an update on the series spinoff? About two years ago, they were going to release a series spinoff, which would be the Rifleman in name only. Lucas had died and Mark was an adult running the McCain ranch.
I think it was supposed to be called: The Rifleman reboot. It was supposed to take place in the late 1880s and Mark was a single father. Anyway, I doubt the pced version would have made it past four episodes.
