She was born Patricia Kara Cameron on September 20, 1948, in Greeley, Colorado, the kind of town that raises you on straight lines, wide skies, and the idea that work is something you do before you ever think about glory. Later she’d be known as JoAnna, sometimes spelled with that stubborn second “A,” a name with a showbiz shine to it, but she started life far from shininess. The family moved through ordinary American air, and she wound up in California by the time the camera found her. She went to college at UC Riverside, not some finishing school for starlets, just a place where you learn to show up and take notes while wondering what the rest of your life is going to cost.
She had the tall, clean beauty of that era’s commercials and magazine ads—those angles that make the light behave. She also had something else, a steadiness that feels physical. The stories say she met Linda Hope in college, Bob Hope’s daughter, and in Hollywood that’s the kind of friend who can open a door just by being in the room. Bob Hope met her and cast her in How to Commit Marriage in 1969, and that first notch on the belt turned into a string of parts through the 1970s. She didn’t crash into the business like a meteor; she slid in like a pro who’d been waiting for a shift to start.
The early roles are a blur of the decade’s TV wallpaper: The Bold Ones: The New Doctors, Marcus Welby, M.D., Columbo, all those shows where even the guest stars had to look like they could survive a close-up in harsh studio light. She had a knack for that. She shows up in Pretty Maids All in a Row, black-comic and slightly sweaty like a Friday night in a bar that never closes. She’s in B.S. I Love You. She’s around, moving through sets, giving a scene weight and then vanishing before the credits roll. That’s the grind. You take the job, you hit the mark, you leave. You build a career brick by brick while the world only notices the house after it’s standing.
Somewhere in there she was rumored to have been considered for Love Story, the role Ali MacGraw got. That’s one of those Hollywood “almosts” that people pin to you like a gold star you never asked for. The same town that hands out “almosts” like parking tickets rarely tells you that getting the role can sometimes be the curse. She didn’t get it. She kept working. She didn’t whine.
Then the weirdest, brightest thing happened. 1975. Saturday morning. Capes and cap guns and cereal bowls on TV trays. She was cast as Andrea Thomas in Isis—a high-school science teacher who finds a magic amulet in Egypt and becomes a superhero by calling out “O mighty Isis!” That’s the premise, and it’s both ridiculous and perfect. Because in that era, women superheroes on television were rarer than a quiet audition room. The show had no slot to hide in. If it failed, it failed loudly. If it worked, it became legend for a certain kind of kid.
She made it work. That’s the plain truth. The costume was Egyptian-goddess-loud—white dress, gold collar, headpiece like a sun on her forehead. But she didn’t play it like camp. She gave Andrea Thomas a real center: smart, kind, authoritative without being stiff. When she turned into Isis, she didn’t wink at the camera. She went straight-faced into the myth. That sincerity is why people still remember her. Kids trust sincerity the way adults never do.
Isis ran two seasons, 22 episodes, and even crossed into Shazam! a few times, because Saturday morning was a shared universe before anybody called it that. It didn’t get a third season, even though it had a loyal audience. That’s show business: the same hand that gives you a crown will take it back because the numbers twitched wrong. In syndication it got renamed The Secrets of Isis, and the title felt like a diagnosis for the whole thing—this shimmering little artifact from the ’70s that people find later like a pressed flower in a book. She became, for a lot of viewers, the first woman they saw on TV who could fly, run faster than panic, and throw bad guys around without apologizing.
When the show ended, she kept moving. She did McMillan & Wife. She showed up in The Amazing Spider-Man, another stop in the era’s low-budget hero lane. She hosted the Navy Network, which is as far from Saturday morning fantasy as you can get without joining the service. She even directed a Navy commercial, Razor Sharp, like she was quietly collecting skills in case the acting door ever shut.
And there was the other job—her real secret identity—commercials. She was everywhere. Shampoo. Pantyhose. Cosmetics. Beer and wine. Breath fresheners. If you watched television in the late ’70s, you probably saw her selling you something without realizing you were watching a superhero pay the rent. Guinness reportedly tagged her with a record: 105 TV commercials. Someone estimated that if you strung them all together, they’d run for about 150 hours. Think about that: nearly a week of continuous JoAnna, smiling at you from the screen, selling you the small comforts of American life. She wasn’t just acting in commercials; she was doing cultural labor. She was a face that made the country feel like it knew itself.
Her last known on-screen role was in the 1980 TV movie Swan Song. She was thirty-two and she walked away from acting on purpose. Not a scandal, not a breakdown on a sidewalk, not a tabloid burial. She retired. That’s a radical move in a town built on people begging to stay. After that she worked for about a decade as a nurse in home healthcare. Imagine the whiplash: from goddess armor to latex gloves, from canned applause to real human need. But it makes a kind of sense. Nurses need the same calm that actors do—show up, do the hard thing, don’t flinch. Only this time the stakes were living bodies, not story beats.
After nursing she moved into hotel marketing and stayed in that world for decades. Another pivot, another proof she wasn’t married to the myth of being famous. She was good at being useful. Hollywood takes a lot from people; she took something from it too—money, discipline, speed—and then used it to build a life off-camera.
She died in Oahu, Hawaii, on October 15, 2021, from complications after a stroke. The news came through old castmates and fans who still carried her in their Saturday-morning heart chambers. She was seventy-three. Some obits called her “trailblazing,” and they weren’t wrong. But trailblazing makes it sound like she was waving a flag the whole time. Most of the time she was just working. The trail comes later, when people look back and realize someone had to be first so the rest could follow without getting laughed out of the room.
That’s what her life looks like when you stop trying to fit it into a neat showbiz narrative. A woman who caught a break through a famous friend, yes, but who held her career through talent and stamina. A woman who became a superhero in a children’s show and played it straight enough that kids believed in her. A woman who then sold the country its everyday dreams for a living. And finally, a woman who walked away from the spotlight and chose a quieter kind of dignity—healing, then building, then living like a person instead of a product.
The town loves a comeback story. She didn’t give it one. She gave something rarer: a clean exit and a second life. When you see her now in old clips, raising her arms and calling for power, don’t just see the costume. See the woman underneath it who knew that the real magic isn’t flying. It’s knowing when to stop flying and still land on your feet.
