No, I remember that show.
This was a later show.
A man / woman team, a spy, intelligence type thing.
I'm sure the talking heads will reference, in relation to this.
I think that was a show called Alias Smith and Jones.
Jon-Eric Hexum was the one who pointed a 'prop' gun at his head. The 'wad' caused head injury and he died.
Peter Duel committed suicide. IIRC, that was at his home, not on the
Alias Smith and Jones TV setting.
