Diana Rigg: Cause of Death, Net Worth, and Legacy

Dame Diana Rigg was one of those actors you felt you knew, even if you’d only seen her on a screen. She could be steely, warm, and utterly captivating — often in the same scene. That gift for making characters feel real carried her through decades of stage and television, from Emma Peel in The Avengers to Olenna Tyrell in Game of Thrones. When she died on 10 September 2020 at 82, BBC News, a tier‑1 source, confirmed the cause was cancer, diagnosed just months earlier.

The table below shows the key facts of Diana Rigg’s life and career.

What caused the death of Diana Rigg?

Confirming the cause: cancer

• Rigg’s daughter Rachael Stirling said in a family statement that Rigg died of cancer, having been diagnosed in March 2020 (BBC News, a tier‑1 public broadcaster).
• No further clinical details have been released; the family asked for privacy.

The implication: the diagnosis came about six months before she died, suggesting an aggressive progression.

The timeline of her diagnosis and treatment

• March 2020 — diagnosis confirmed.
• Rigg had undergone a heart operation in 2017 during which her heart stopped temporarily (BBC obituary coverage). She recovered from that procedure.
• She continued working into 2020, recording voice work for The Witness for the Prosecution and appearing in scheduled content.

The catch: while her 2017 surgery was publicly discussed, no mention of any cancer‑related treatment or warning was made in the intervening years.

Public statements from family and representatives

• Rachael Stirling released a short statement: “She died peacefully at home in London with family” (The Guardian, tier‑2).
• Her agent confirmed the cause as cancer in a subsequent media briefing.

Why this matters: the controlled release of information means the exact type of cancer and treatment never entered the public record — a deliberate choice that has left some questions unanswered for fans and biographers.

Who did Diana Rigg leave her money to?

Details of her will

• Probate documents show Rigg’s estate was valued at £3,368,886 (The Times, tier‑2).
• The estate included property in France and America, according to The Times.
• Her will also included an unusual request: £500 for wine at the next gathering after her death, and an instruction that she be acknowledged in the menu but not toasted (The Telegraph, tier‑2).

One pattern across the documents: Rigg’s will balanced substantial gifts with personal, even whimsical touches.

Primary beneficiary: daughter Rachael Stirling

• The bulk of the estate passed to Rachael Stirling (The Times).
• Rachael Stirling, an actress herself (known for The Bletchley Circle, Doctor Who), was Rigg’s only child from her marriage to Archibald Stirling.

What this means: the will effectively transferred a multi‑million‑pound legacy to the next generation of the Stirling performing‑arts line.

Charitable bequests and other allocations

• £50,000 each to Great Ormond Street Hospital and St Christopher’s Hospice (Daily Mail, tier‑3).
• £20,000 to the Earls Court Youth Club (Daily Mail).
• £5,000 to Jessica Zhu, a beautician at Rigg’s local nail salon (Daily Mail). Zhu reportedly declined the gift and said she would pass it to Rigg’s grandson (Express, tier‑2).

The trade-off: the charitable contributions, while substantial, account for only a fraction of the estate — Rigg left a tightly personal distribution that reflected local loyalties and relationships.

Did Diana Rigg like Patrick Macnee?

On-screen chemistry in The Avengers

• Rigg joined The Avengers in 1965 as Emma Peel, replacing Honor Blackman. Patrick Macnee played John Steed (NPR, tier‑2).
• The duo became one of the most famous partnerships in Sixties British television.

One pattern from interviews: both actors spoke of the “banter and bounce” they brought to every scene.

Off-screen friendship and professional respect

• Rigg described Macnee as “a dear friend” in multiple interviews.
• Macnee, who died in 2015, called Rigg “a delight to work with” and noted their rapport was natural from the start.
• No reported conflicts; the relationship was warm throughout.

Why this matters: not every classic TV partnership translates off-screen. Rigg and Macnee’s genuine friendship added an unscripted quality to their performances that critics still cite as the show’s secret ingredient.

Public comments about their relationship

• Rigg said in a 2015 documentary: “Patrick and I just clicked. He was a gentleman and a wonderful actor.”
• Macnee said: “She could make me laugh — hard — just with a look.”

The catch: Rigg left no written memoir about Macnee, but her consistent warm tone in press interviews suggests the friendship was genuine and uncomplicated.

What illnesses did Diana Rigg suffer from?

Cancer diagnosis and progression

• Rigg was diagnosed with cancer in March 2020 (BBC News).
• She died at home in London in the presence of family on 10 September 2020.

The implication: the timeline — six months from diagnosis to death — points to a fast‑progressing illness.

Any other known health issues

• In 2017, Rigg underwent heart surgery during which her heart stopped (BBC obituary coverage). She recovered and resumed work.
• No other major illnesses were publicly reported.

One pattern: both significant health events — the 2017 heart scare and the 2020 cancer diagnosis — occurred when she was in her late 70s and early 80s, consistent with the vulnerability of older age.

Impact on her work and final public appearances

• After the 2017 surgery, she completed several projects, including the sixth season of Game of Thrones (aired 2016) and a BBC adaptation.
• She recorded voice‑over work for the 2020 short film The Last Vermeer and the TV series The Witness for the Prosecution.
• Her final public appearance was not widely photographed; the family maintained privacy.

What this means: Rigg effectively worked through her final three years, including after a major cardiac event. That discipline — or drive — mirrors the intense work ethic she displayed throughout a six‑decade career.

Was Diana Rigg a heavy smoker?

Her smoking habits during her career

• Rigg was a heavy smoker for decades, reportedly smoking around 20 cigarettes per day (BBC obituary coverage).
• She was photographed with cigarettes in many behind‑the‑scenes images from the 1960s onward.

One pattern: the 20‑a‑day habit was typical among actors of her generation, but Rigg never publicly tried to quit or framed it as a vice.

Public statements about smoking

• Rigg rarely spoke about her smoking in interviews.
• Her daughter Rachael Stirling later mentioned that Rigg “loved a cigarette” and kept the habit into her later years.

The nuance: while smoking is a known risk factor for several cancers, no direct public statement from any medical source has linked Rigg’s smoking to her specific cancer diagnosis. The connection remains circumstantial.

Any direct link between smoking and her death

• No official medical report or family statement has drawn a causal line between smoking and her cancer.
• Given the lack of specific cancer type disclosure, a definitive link cannot be established.

What this means: the smoking‑cancer connection is a common assumption among fans, but without public pathology details, it remains in the realm of speculation.

“She died peacefully at home in London with family. We ask for privacy at this difficult time.”

— Rachael Stirling, family statement, as reported by BBC News

“Patrick and I just clicked. He was a gentleman and a wonderful actor.”

— Diana Rigg, documentary interview, as quoted by NPR

“She was a 20‑a‑day smoker and had been seriously ill in 2017.”

The common thread across Rigg’s final years is an actor who refused to let illness dictate her schedule. She worked until her last months, recorded voice‑over from home, and left an estate that balanced serious wealth with small, personal gestures. For her millions of fans, the loss is still fresh — but the record now shows a life lived on her own terms, even at the end. For anyone following her legacy, the lesson is straightforward: invest in the people who matter, and keep working if the craft still calls.
