Seven key facts about Jeremy Brett, from birth to legacy:

What illness did Jeremy Brett have?

Jeremy Brett suffered from a combination of mental and physical health conditions that worsened during the last decade of his life. The most commonly cited ailments are bipolar disorder (manic depression) and cardiomyopathy leading to congestive heart failure.

What was the cause of Jeremy Brett’s death?

• Brett died of heart failure at his home in Clapham, London, on 12 September 1995 (The Independent (UK newspaper)).
• His heart valves had been scarred by rheumatic fever contracted in childhood, according to a fan biography (A Posthumous BAFTA For Jeremy Brett (fan tribute)).
• IMDb describes the death as iatrogenic congestive cardiac failure, though this is a low-confidence claim (IMDb (industry database)).

Did Jeremy Brett’s illness affect his acting?

Yes—visibly. The Birmingham Mail reported that Brett’s deteriorating health and appearance during the last decade of his life were unmistakable on screen (Birmingham Mail (regional news)). He was a heavy smoker—up to 60 cigarettes a day—which compounded his heart problems.

Bottom line: Brett’s illness was a mix of bipolar disorder and heart disease, both of which worsened after 1985. His death from heart failure at 61 cut short a career that had already been compromised by his health.

The implication: the physical toll of method acting, combined with serious illness, created a tragic arc that defined his final years.

Why did Jeremy Brett gain weight?

Weight gain is one of the most discussed physical changes in Brett’s later Holmes episodes. The cause is tied directly to his medical treatment.

Was the weight gain due to medication?

• Medication for bipolar disorder and heart conditions often causes weight gain as a side effect (IMDb (industry database)).
• Brett also struggled with depression and overeating, which contributed to his changing physique (Wikipedia (free encyclopedia)).

How did weight gain affect his portrayal of Holmes?

The change was noticeable. Season 1’s Holmes was lean and sharp; by the later Granada TV episodes, Brett had visibly filled out. Critics and fans often commented on the shift, but Brett’s performance remained intense. The editorial verdict: his physical transformation was a side effect of survival, not a loss of artistic commitment.

The pattern: the same treatments that sustained his life also reshaped the iconic look that defined his role.

How many episodes did he star in?

Brett appeared in 41 episodes across the Granada TV series, making him the actor who played Sherlock Holmes in the most television episodes on British television.

What was his legacy?

Brett’s Holmes is widely considered the definitive screen version. The physical toll he paid—both the visible weight gain and the ultimate cost of his life—adds a tragic depth to his legacy. For fans, his performance remains the gold standard.

Bottom line: Brett didn’t stop playing Holmes because he wanted to—he stopped because his body gave out. He died at 61, leaving behind a body of work that defined a character for a generation.

The catch: the role that made him immortal also hastened his decline.

Brett’s story is not just about a great actor—it’s a reminder that the most iconic performances often exact a personal price.
