It was 1974. Half of America—literally, like 50 million people—tuned in to watch a fictional wedding. Rhoda Morgenstern was finally getting her happy ending. But if you talk to any die-hard fan of the Rhoda TV series cast, they’ll tell you that the wedding was actually the beginning of the end.
The show was a spin-off of The Mary Tyler Moore Show, taking the sharp-tongued, self-deprecating best friend out of Minneapolis and dropping her back into the chaotic embrace of her Jewish family in New York City. It was an instant smash. It’s actually still the only series in TV history to hit number one in the ratings with its very first episode.
But then, the writers made a choice. They took the "single girl" energy that made Valerie Harper a star and traded it for a domestic life that honestly didn't fit. Within a few seasons, the marriage was dead, the ratings were tanking, and the cast was in a state of constant flux.
The Core Players: Who Really Made the Show Work?
When people think of the Rhoda TV series cast, Valerie Harper is obviously the face of it. She won four Emmys for playing Rhoda (three as a supporting actress on Mary Tyler Moore and one as the lead here). She brought this incredible, neurotic vulnerability to the screen. She was the everywoman who didn't quite have her life together, and we loved her for it.
But the real magic often happened in the scenes where she wasn't the focus.
Julie Kavner as Brenda Morgenstern
Most people today know Julie Kavner as the voice of Marge Simpson. It's wild to think about, but Rhoda was actually her first professional acting gig. She played Brenda, Rhoda’s younger, deeply insecure sister who worked at a bank.
If Rhoda was the "pretty" one who finally found a guy, Brenda was the one struggling in the trenches. Kavner's delivery was impeccable. She had this "honeyed gravel" voice even back then, and her chemistry with Harper was the emotional spine of the show. She won an Emmy in 1978, right as the show was breathing its last breath.

Nancy Walker and Harold Gould (The Parents)
You can’t talk about this cast without Ida and Martin. Nancy Walker was a force of nature as Ida Morgenstern. She was the quintessential overbearing mother, but Walker played her with such comedic timing that you couldn't help but love her. Fun fact: she was actually filming another show, McMillan & Wife, at the same time. She was so busy she eventually left Rhoda to star in her own short-lived sitcom before coming back.
Harold Gould played Martin, the patient, slightly henpecked father. He was the calm in the Morgenstern storm. Gould was actually supposed to play the dad on Happy Days, but he had a theater commitment, so he did Rhoda instead.
The Joe Gerard Controversy: Why David Groh Was Written Out
This is where the drama gets real. David Groh played Joe Gerard, the handsome, rugged guy who ran a wrecking company. He was the one Rhoda moved to New York for.
The fans adored Joe and Rhoda. Their wedding episode was a cultural phenomenon. But the producers felt that once Rhoda was married, she lost her "edge." They thought a happy, settled Rhoda was boring.
So, in Season 3, they did the unthinkable. They had Joe and Rhoda separate.
- The Backlash: CBS got thousands of angry letters.
- The Sympathy: David Groh actually received "condolence cards" in the mail from fans who thought he was actually getting a divorce.
- The Exit: By Season 4, Joe was gone. The divorce was finalized off-screen.
Honestly, the show never recovered. The ratings plummeted from #7 to #32 almost overnight. People felt betrayed. They had invested in this romance, and the writers just ripped the rug out from under them because they didn't know how to write a "happy" woman.

The Voice We Never Saw: Carlton the Doorman
One of the most iconic members of the Rhoda TV series cast was someone we almost never saw on screen. Carlton the Doorman was voiced by Lorenzo Music.
He was the drunk, slurred-speech doorman who communicated through the intercom. He’d buzz Rhoda’s apartment and say, "Hello, this is Carlton, your doorman." Music was actually a writer and producer on the show, but his voice was so perfect they kept him as a recurring "character."
If that voice sounds familiar, it should. Lorenzo Music went on to be the original voice of Garfield the cat. You can totally hear the "I hate Mondays" energy in Carlton’s lazy intercom greetings.
The Supporting Cast Shuffle
As the show struggled to find its footing after the divorce, they kept throwing new characters at the wall to see what would stick.
- Gary Levy (Ron Silver): The neighbor and friend who was sort of a platonic foil for Rhoda.
- Benny Goodwin (Ray Buktenica): Brenda's long-term boyfriend who eventually became her fiancé.
- Jack Doyle (Kenneth McMillan): Rhoda's boss in the later seasons when she started her own window-dressing business.
What the Cast Taught Us About 70s Television
Looking back, the Rhoda cast was a masterclass in character-driven comedy. They didn't rely on wacky stunts; they relied on the "kvetching" and the awkwardness of family dynamics.
The show was revolutionary for its time because it portrayed a Jewish family with a level of specificity that wasn't common on network TV. It also tackled the reality of a failing marriage at a time when sitcoms usually ended with everyone smiling.

But the "limitations" were clear. The industry in 1977 didn't think a lead female character could be interesting if she was successfully married. They thought the comedy came from the struggle to find love, not the reality of maintaining it.
Where Are They Now? (The Bittersweet Reality)
Sadly, much of the main Rhoda TV series cast has passed away.
- Valerie Harper fought a very public and brave battle with cancer before passing in 2019 at age 80.
- David Groh died in 2008.
- Nancy Walker and Harold Gould are also gone, leaving behind massive legacies in theater and film.
- Julie Kavner is the most prominent survivor, though she is famously private. She rarely does interviews and focuses almost entirely on The Simpsons.
If you're looking to revisit the show, it's a fascinating time capsule. You can see the shift in 70s fashion, the changing landscape of New York City, and the evolution of the "independent woman" trope.
Next Steps for Fans:
If you want to dive deeper, I recommend looking for the 1984 "Rhoda Reunion" on Hour Magazine which you can occasionally find on YouTube. It was one of the few times the main cast got back together to talk about the "Joe and Rhoda" fallout. Also, check out the TV movie Mary and Rhoda from 2000; it’s a bit cheesy, but seeing Harper and Moore together one last time is worth the watch.
To truly understand why this cast worked, watch the first season and then skip to the separation episode "The Separation." You'll see the exact moment the chemistry of the show shifted, for better or worse.
