However, there were a few spin-offs and revivals of the show that Nimoy did participate in:
* In Search Of... with Leonard Nimoy (1994-1995): This version of the show featured Nimoy as the host and narrator, taking viewers on new investigations into unexplained phenomena.
* In Search Of... with Leonard Nimoy (2002): This was a one-off special hosted and narrated by Nimoy for the Sci-Fi Channel, which focused on the legend of the Loch Ness Monster.
So, while Nimoy wasn't involved in the original run, he definitely lent his distinctive voice to the "In Search Of..." franchise for a few years.
