When Richard Gilliland passed away in March 2021, the news hit the entertainment world with a quiet, heavy thud. He wasn't just a face from "Designing Women" or "24." He was the bedrock of a Hollywood marriage that actually lasted—34 years with the legendary Jean Smart. But the details surrounding his passing remained vague for a long time. People kept asking: what was the actual richard gilliland cause of death?
For months, the official line was simply a "brief illness." That’s the kind of phrase that usually fuels the rumor mill. Honestly, in the middle of a global pandemic, everyone just assumed it was COVID-19.
It wasn't.
The Reality Behind the "Brief Illness"
It turns out the truth was much more sudden and, frankly, a bit more frustrating. Richard Gilliland died of a heart condition. Specifically, he suffered from a heart attack, but the path leading up to that moment was a series of missed signals and medical red flags.
Jean Smart eventually opened up about the ordeal, and her account is pretty gut-wrenching. She recently shared that Richard had been complaining of pain when taking deep breaths.
You’ve probably been there—thinking a nagging pain is just a pulled muscle or maybe a lingering cough. Because it was 2021, the immediate concern was virus testing. Smart took him to several places to get tested for COVID. They did the swabs. They checked the boxes.
But they didn't check his heart.

A Missed EKG and a Fatal Delay
This is where the story gets heavy. Smart later recounted going back to one of the medical facilities after he died. She asked a simple question: "If I brought in a 71-year-old man complaining of pain during deep breaths, what would you do?"
The answer she got? "The first thing we'd do is an EKG."
That EKG never happened.
By the time Gilliland was finally admitted to a hospital, things had spiraled. He suffered a heart attack while in medical care. Because of the delay and the complications that followed—including the development of pneumonia—doctors couldn't perform the surgery he needed. They tried to buy him time by putting in a stent, hoping to stabilize him long enough to treat the pneumonia and then operate.
It didn't work. He died on March 18, 2021, at the age of 71.
Why Richard Gilliland Still Matters
Richard wasn't just "Jean Smart’s husband." He was a prolific character actor. You might remember him as JD Shackleford, the on-again, off-again boyfriend of Mary Jo Shively on Designing Women. That's actually where he met Jean. She reportedly asked a co-star to find out if he was single.
They were a team.
He often put his own career on the back burner so Jean could shine. While she was winning Emmys and starring in Hacks or Watchmen, Richard was the one keeping the home front steady for their two sons, Connor and Forrest.
The Connection Between His Death and Jean Smart’s Health
There is a strange, sobering footnote to this story. In early 2023, Jean Smart revealed she had undergone a heart procedure of her own. She’s fine now, but she admitted the decision to get checked out was driven entirely by the trauma of losing Richard.

She felt a "nagging" sensation while filming a scene for Hacks. Instead of brushing it off like many of us do, she thought of her kids. She didn't want them to be orphans.
What We Can Learn From This
The richard gilliland cause of death isn't just a piece of celebrity trivia. It’s a pretty stark reminder about how heart disease masks itself. It doesn't always look like a dramatic chest-clutching moment from a movie. Sometimes it looks like:
- Pain when taking a deep breath.
- Persistent fatigue.
- A "brief illness" that doesn't quite feel like a cold.
If you’re over 50—or honestly, at any age—and something feels "off" in your chest or breathing, don't just ask for a viral swab. Ask for the EKG.
