Screen Gems took a chance with All About Faces, which was a bit of an early bird, debuting before Labor Day in 1971, but lasting just 1 year. The series was produced in Canada, and distributed in both Canada & the US by Screen Gems. As memory serves, one of the local stations coupled Faces with the syndicated revival of What's My Line? in an early afternoon block.
The concept was part quiz, part Candid Camera, with the use of a hidden camera. Richard Hayes (ex-The Baby Game) served as host. To me, the show deserved a better fate than it got. I can't speak for the rest of the country, but I'd guess that Faces failed because Candid either was still on the air or had recently ended, and was still fresh in people's minds.
Here's a sample all-star episode, with Steve Allen, Jayne Meadows, Jacqueline Susann, and & Irving Mansfield.
By the time GSN got its hands on Faces, they were, as you can see, compressing closing credits for ad purps. Not good.
