His birth father died when Brent was less than a year old, so he took his adopted father’s name “Mintz” from 1955-1975 before finally reverting back to “Spiner.”
AFAIK Spiner wasn’t actually a photographer as he claimed, but a stage actor living in NYC at the time. Twelve years after the above appearance, he moved to LA and began playing a recurring character on Night Court, “Bob Wheeler,” as well as other roles.
This game show is definitely showing its age, and I do find it amusing that they used not just such an ordinary-looking host, but one who also looked about ready for the retirement home. But he does in fact do a fine job I think, and the show itself has a very interesting premise, one in which a panel must try to pick between two imposters and a genuine person.
I thought that was a big part of how Spiner made Data just about the most interesting character in the series-- the understated little flourishes, tics, and burblings of emotion showing through.
To me a very clever variation on Nimoy’s amazing work on Spock in the series before, but of course Brent made the character wholly his own to the point that it barely registered that he was cut from the ‘Spock template.’
