1. Jan Harrison

Harrison is likely the actress sitting on the sofa with Astin as Morticia. She is best remembered as the most frequent female guest star on Sea Hunt with Lloyd Bridges. She was also married (briefly) to racing legend Carroll Shelby, but the two split a couple years before this photo shoot.

2. Paul Wexler

Wexler is a dead-ringer for James Cromwell, albeit a generation older. With his towering stature (6' 6") and deep voice, he was an apt option for the lumbering Lurch. He also had roots in horror, notably as the zombie in 1959's The Four Skulls of Jonathan Drake.

3. John Dierkes

With his craggy, grizzled face, Dierkes would have cut a much different figure as the manservant Lurch. His resume largely consisted of Westerns and sci-fi fare, in everything from The Oregon Trail to Abbott and Costello Meet Dr. Jekyll and Mr. Hyde. With that strong jaw, he could have made a great Poopdeck Pappy, Popeye's dad.

4. Josip Elic

Let's finish the trio of would-be Lurches with Elic, a character actor with a long list of credits that include the Twilight Zone episode "The Obsolete Man" (seen here) and One Flew Over the Cuckoo's Nest. He made for a more comical-looking Lurch.

5. Stanley Adams

Hey, at least they looked at someone named Adams for the Addams! This actor is most widely recognized as Cyrano Jones in Star Trek, the trader in "The Trouble with Tribbles." You might not recognize him without his hair, under that pancake makeup, as Uncle Fester.

6. Tracy Stratford

Now we come to Wednesday — well, the Wednesdays. The one on the far right is Tracy Stratford, the little girl with the "Living Doll" in The Twilight Zone, seen here. She was also the voice of Lucy in A Charlie Brown Christmas!

7. Jimmy Garrett

Outside of Astin, Garrett was perhaps the most experienced sitcom actor in the pool of candidates, oddly. He had previously played the son of Lucy, Jerry Carmichael, on The Lucy Show. That's probably him on the left in this quartet of potential Pugsleys.

8. Eileen O'Neill

We feel pretty confident about the identities of these candidates. The Morticias remain perhaps the most perplexing. We agree with others in thinking that the one on the far right here is O'Neill, who would turn up as Violet on Bewitched. She had also been in Burke's Law.

9. Joan Huntington

Most of the attention and trial-and-error was paid to Morticia, obviously, as she would truly be the star of the show. Huntington, seen here as a villain on The Wild Wild West, was seemingly one of the Morticia try-outs.

As for the other Morticias? Well, your guesses are as good as ours. Debra Paget and Charlene Holt are names bandied about. Tell us what you think in the comments!
