You must be under 50.
“Armando Joseph Catalano (January 14, 1924 – April 30, 1989), better known as Guy Williams, was an American actor and former fashion model.
He usually played swashbuckling action heroes in the 1950s and 1960s, but never quite achieved movie-star status.[2]
Among his most notable achievements were two TV series: Zorro in the title role, and as the father of the Robinson family on the popular sci-fi series Lost in Space.”

No, I’m way over 50. I was testing you, lol. Williams does kinda resemble Lazenby in toy form in that bottom image. Most people don’t know who Lazenby is. I used to watch Lost and Space before I became a Star Trek fan which was a more serious show.
