Oldest Movie (or TV show) with all primary cast still alive

Inspired by this thread, what is the TV Show/ ldest movie where all the primary actors/actresses are still living.

My TV history (via Nick-at-Nite) goes back to mid 60’s and I can’t think of any show that has all the cast still alive.
Also, partly inspired that it is time to start think about Death Pool picks, and I might want to go with a theme.

Working from the lists at FiftiesWeb we can eliminate all of the top shows right up until 1959 when we get to 77 Sunset Strip. Efrem Zimbalist Jr., Roger Smith, Edd “Kookie” Byrnes and Jacqueline Beer are all still alive. Though The Life and Legend of Wyatt Earp might count, as its main cast was just one man, Hugh O’Brian, who’s still kicking at age 87. I think that defeats the spirit of the question, though.

I need a break before I check on movies…

Oops, could a mod fix my link, perhaps? I got ahead of myself on the tags.

Louie Quinn is daid.

They dont count, because there are no reruns of these two shows.

77SS is currently in reruns on MeTV in Chicago.

The Six Million Dollar Man (1974-1978) still has its entire cast - Lee Majors, Richard Anderson, Alan Oppenheimer, Martin E. Brooks, Lindsay Wagner, and Jennifer Darling - alive.

Quinn appeared in only about 1/3 of the episodes though. Does that make him “primary cast?” I don’t think so. And actually, by that logic, Jacqueline Beer doesn’t really count either, but she was the most primarily featured woman, so I included her in my calculation.

Who said anything about reruns?

I looked up the original Lord of the Flies and the actor who portray Ralph died earlier this year.

So Lord of the Flies is out.

However, I think The Partridge Family qualifies. All the kids are still alive as well as Mom and Reuben.

How about The Sound of Music from 1965?

Julie Andrews, Christopher Plummer, and all the kids are still alive.

I Dream of Jeannie?

Hayden Roarke who played Doctor Bellows is no longer with us.
