As mentioned in the book "Barnabas and Company: The Cast of the TV classic Dark Shadows", Laurette Spang did a little match-making between two of her friends, and they eventually married.
Jerry Lacy (
Dark Shadows (1966)) and
Julia Duffy (
Newhart (1982)) had both worked on the soap
Love of Life (1951), but they never appeared together on that show, and barely knew each other. When Laurette visited New York to make a TV movie, she brought the two together. They began dating, and eventually married.
