Jeremy Brett: Bipolar Disorder, Marriages, and Holmes Legacy

Few actors become so inseparable from a character that the two names blur into one. Jeremy Brett’s Sherlock Holmes, which ran for 41 episodes between 1984 and 1994, set a benchmark that few have challenged.

Born: 3 November 1933 ·
Died: 12 September 1995 ·
Known for: Sherlock Holmes (1984–1994) ·
Spouses: Anna Massey (1958–1962), Joan Wilson (1976–1985) ·
Children: 1 (David Brett)

Eight key facts capture the arc of Brett’s life — from birth to lasting legacy.

What illness did Jeremy Brett have?

Bipolar disorder diagnosis

Jeremy Brett was diagnosed with manic depression (now called bipolar disorder) in the 1970s and was treated with lithium (Wikipedia (online encyclopedia)). The condition caused severe mood swings that became increasingly visible during the late 1980s, especially after the death of his second wife.

Heart condition and cardiomyopathy

Brett also suffered from cardiomyopathy, which led to congestive heart failure. According to IMDb (film database), his heart valves were permanently scarred by rheumatic fever he endured as a teenager. Medication prescribed for bipolar disorder, along with his lifelong smoking habit, further weakened his heart. He died of heart failure on 12 September 1995 (The Sherlock Holmes Society of London (Sherlockian society)).

Impact on his acting career

The combination of mental and physical illness made filming increasingly difficult. Brett’s commitment to Holmes was intensified by his struggles — a personal account notes that his bipolar disorder and physical strain deepened his portrayal (SherlockHolmes.com (fan site)). Yet the same illness that gave his performance raw intensity also shortened his career.

The pattern: Brett’s health was a double-edged sword — it fueled an obsessive dedication to Holmes but eventually consumed the man behind the role.

The implication is clear: illness gave his performance raw intensity but shortened his career.

How is Martin Clunes related to Jeremy Brett?

Marriage to Joan Wilson

Jeremy Brett married Joan Wilson in 1976. Joan had a son, Martin Clunes, from a previous marriage. Brett became Clunes’ stepfather (Wikipedia (online encyclopedia)). The marriage lasted until Joan’s death from cancer in 1985, a loss that devastated Brett.

Stepfather-stepson relationship

Martin Clunes, now a well-known English actor himself, was raised in part by Brett. The two maintained a familial bond, though Clunes has spoken little about the relationship publicly.

Martin Clunes’ career

Martin Clunes is best known for his roles in Doc Martin and Men Behaving Badly. He has built a successful career independent of Brett’s shadow, but the connection remains a point of curiosity for fans of both actors.

The implication: Through Joan Wilson, Brett gained a stepson who would go on to become one of Britain’s most beloved television actors — a quiet legacy beyond the deerstalker.

Did Jeremy Brett ever marry?

First marriage to Anna Massey

Brett married actress Anna Massey in 1958 (The Sherlock Holmes Society of London (Sherlockian society)). The marriage lasted four years, ending in divorce in 1962. Anna Massey was a respected stage and screen actress.

Second marriage to Joan Wilson

His second marriage was to Joan Wilson in 1976. She was a television producer and the mother of Martin Clunes. The couple remained together until Joan’s death from cancer in 1985, a blow from which Brett never fully recovered.

Later life and widowhood

After Joan’s death, Brett did not remarry. He lived the last decade of his life as a widower, grappling with his health and losing himself in the role of Holmes.

The trade-off: Brett’s two marriages bookended his emotional stability — the first ended quickly, the second ended too soon, leaving him alone to face the most demanding role of his life.

Why did Jeremy Brett stop playing Sherlock Holmes?

Health deterioration

Brett’s physical and mental health declined steadily through the late 1980s and early 1990s. His heart condition, compounded by bipolar disorder, made the strenuous filming schedule unsustainable. He was hospitalized several times in his final years (Tribute blog (fan site)).

Death of Joan Wilson

The loss of his wife in 1985 triggered a nervous breakdown in 1986 (Wikipedia (online encyclopedia)). That breakdown marked a turning point; Brett’s ability to cope with the pressures of the role diminished sharply.

End of Granada series

The Granada television series ended in 1994 after six series and a total of 41 episodes. The network did not renew the show, partly due to Brett’s declining health. He was simply unable to continue at the required pace (IMDb (film database)).

Final episodes

The final episodes showed a visibly thinner, wearier Holmes — but also a performance of remarkable emotional depth. Brett’s illness, far from ruining his work, gave his last scenes a haunting realism.

The catch: Brett stopped playing Holmes because his body and mind gave out, but the raw authenticity of those final performances is exactly why they remain unmatched.

Later episodes show his vulnerability—a final testament to his dedication.

When did Jeremy have his accident?

Nervous breakdown of 1986

The “accident” often referenced in fan forums is not a physical mishap but a nervous breakdown in 1986. Following the death of his wife Joan, Brett suffered a severe episode of bipolar disorder and was hospitalized (Wikipedia (online encyclopedia)).

Effects on filming schedule

The breakdown forced a hiatus in the production of The Return of Sherlock Holmes series. Filming was delayed while Brett underwent treatment — a rare interruption for a television series of that era.

Recovery and later health

Brett returned to work but was never fully well. He accepted that his condition would require lifelong management, as noted in a biography posted by fans (Tribute blog (fan site)). The breakdown reshaped his approach to Holmes, adding a layer of personal pain to the character’s cold logic.

Why this matters: The 1986 breakdown marked the beginning of a decade-long struggle that would define the last years of Brett’s life — and deepen his legacy as the definitive Holmes.
