Vivien Leigh and Boy, the Siamese who slept on the set of A Streetcar Named Desire

On the Warner Bros. lot in Burbank, California, in the fall of 1950, Elia Kazan was directing a 37-year-old British actress through one of the hardest films of classic American cinema. Behind the cameras, in the chair with her name on it, an adult seal point Siamese slept curled on a cushion. When the actress finished a take, before she even wiped off the exhausted makeup of Blanche DuBois, she would come collect him and carry him back to her dressing room. He was her cat. She had brought him across the Atlantic from Notley Abbey in England, and his name was Boy.

The actress was Vivien Leigh, the film was A Streetcar Named Desire (1951), based on the Tennessee Williams play, and the cat became one of the best-documented animals of Hollywood's golden age. Boy's presence on the shoot appears in at least three later scholarly biographies and in correspondence held at the British Library. A Siamese in the middle of an electric drama, and what his presence reveals about Leigh carries far more weight than any set anecdote.

The actress who was no longer Scarlett

To understand why Boy was on that set, recall where Vivien Leigh stood in 1950. She had won the Academy Award for Best Actress eleven years earlier for Gone with the Wind (1939). She had lived through worldwide fame. Between 1944 and 1945 she had suffered a serious case of pulmonary tuberculosis that kept her off work. She had been diagnosed, in the terminology of the day, with "manic-depressive psychosis," what is now called bipolar I disorder, in one of the first widely documented cases in a British public figure.

Anne Edwards documents in Vivien Leigh: A Biography (Simon & Schuster, 1977) that Leigh's manic episodes recurred every two or three years, lasting weeks or months, and followed a predictable pattern. Severe insomnia, hypersexuality, verbal agitation, rapid physical decline, followed after the manic phase by deep depression with suicide risk. Between episodes, though, Leigh was a brilliant actress, a voracious reader, an impeccable social hostess, and, less famously, one of the great English devotees of Siamese cats at midcentury.

Boy and the Siamese gallery of Notley Abbey

Notley Abbey was the former twelfth-century Cistercian abbey that Vivien Leigh and her then-husband Laurence Olivier had bought in 1944, in Buckinghamshire, England. Three floors, grounds of roughly 170 acres, a substantial library. Through the 1940s and 1950s several Siamese cats lived in that house, bred by Leigh with some method.

Boy was one of the best-documented of those Siamese. He was a classic seal point: ivory-cream body with mask, ears, legs, and tail in a dark, near-black brown (the seal color in Siamese terminology), and deep blue eyes. Medium build, adult weight around 9 to 10 lb (4 to 4.5 kg) by the physical descriptions in the biographies. Temperament typical of the breed: very vocal, demanding of attention, intensely bonded to one particular person.

Hugo Vickers, in his biography Vivien Leigh (Hamish Hamilton, 1988), describes how Boy followed the actress around the house, slept on her bed, and behaved with marked suspicion toward new visitors. He was Leigh's closest cat within the Notley Siamese colony. When she agreed to cross the Atlantic to film Streetcar, she decided to take him along. Olivier stayed in England filming Carrie with William Wyler.

Why did Boy travel to California?

Moving a European cat to the United States in 1950 was no small thing. The bureaucratic pet-passport systems of today did not exist, but mandatory quarantine, health certificates, and air restrictions did. Leigh arranged the trip through the agency that handled her professional travel. The cat flew with the actress, in a carrier she kept under her seat during the transcontinental flights with their layovers.

Why the effort? Edwards offers a concrete answer. The character of Blanche DuBois in Streetcar was the most psychologically demanding role Leigh had ever taken on. A broken woman, a faded Southern aristocrat, an alcoholic, trapped in the home of her sister and her violent brother-in-law Stanley Kowalski (played by Marlon Brando). For an actress with documented bipolar disorder, playing a woman in psychic crisis was a real emotional hazard. Her London psychiatrist had advised keeping every available anchor of stable daily routine during the shoot. Boy was one of those anchors.

The choice was no actress's eccentricity. It worked as an indirect therapeutic prescription. Leigh knew the cat's constant presence helped her regulate the day. The ritual of feeding him at a set hour, the ritual of brushing him at night, the ritual of having him in the dressing room between takes. The kind of daily structure that a film set, with its chaotic schedules and continuous tension, rarely offers on its own.

The set

Kazan was a director known for the intense emotional climate he cultivated on his shoots. Streetcar was filmed at Warner studios through the fall of 1950, with long days, intensive Method rehearsals (Brando came out of the Actors Studio), and clashes of acting styles between the American actors and the British star.

In that atmosphere, Boy held a fixed corner of the set. Walker (Vivien: The Life of Vivien Leigh, Weidenfeld & Nicolson, 1987) repeats a specific anecdote drawn from an interview with a Warner production assistant: the Siamese had his cushion in the area reserved for Leigh, received water and small portions of cooked chicken from catering, and the actress came to check on him during every break. Kazan, by that account, raised no objection. Brando, known for a difficult temperament, seems to have accepted the animal without a hostile word. The set photographs published later do not show the cat often, but at least two images catch him in Leigh's lap during a break.

The shoot wrapped in December 1950. Leigh won her second Best Actress Oscar for the performance in March 1952. Boy returned to Notley Abbey with her after filming.

The matter of the name and the succession: Blanche

Here comes a lesser-known detail. After the success of Streetcar, Leigh decided to rename one of her Siamese cats Blanche, in honor of the character. Which exact cat received the new name has caused some confusion in later biographies, but the best-supported version (Vickers, Walker) is that it was one of the Notley females, a daughter or niece of Boy. Boy kept his original name. The new Blanche was a seal point female who replaced Boy as the favorite animal in the years that followed.

The detail reveals how Leigh processed her characters. She did not drop them when filming ended. She folded them into her domestic life. Blanche DuBois, a woman defeated by reality and sheltering in fantasy, came to have her feline counterpart at Notley Abbey, sleeping on the library armchair, with Leigh calling her by the character's name as a daily reminder of that performance. For an actress with Leigh's psychic makeup, that mechanism of prolonging the character could cut both ways: a creative anchor, but also a risk of over-identification.

The Siamese breed, brief context

The mid-century Siamese, as Boy embodied it in 1950, was a sturdier cat with a rounder head than the contemporary show Siamese. The breed has shifted morphologically over recent decades toward an extreme type (a very triangular head, a very elongated body, known as the modern or show Siamese), while the moderate twentieth-century type survives today under the name Thai or traditional Siamese.

Boy belonged to the traditional type. Adult weight between 9 and 11 lb (4 to 5 kg), a moderately apple-headed skull, a muscular but not extreme body. Seal point color, the oldest of the recognized point colors in the breed (chocolate, blue, and lilac points reached standard recognition in later decades). Typical breed lifespan: 12 to 15 years, with documented cases reaching 18 to 20 in well-cared-for cats.

Health concerns to watch in Siamese: hepatic amyloidosis, certain hereditary dental problems, feline asthma, and in the extreme modern type, strabismus and other eye conditions. Leigh's Notley Abbey line came from respected English breeders of the period, and the animals had regular veterinary care. No serious illness is documented in Boy.

Boy and Leigh's manic-depressive phase

The year 1953 marked one of Vivien Leigh's most severe psychiatric crises. During the shoot of Elephant Walk in Ceylon (today Sri Lanka), the actress had a severe manic episode that forced her to be replaced by Elizabeth Taylor. She returned to England in collapse. Boy and the Notley Siamese, in testimony collected by Vickers, were steady company through her recovery.

Edwards documents a telling scene. In the middle of one of the post-manic depressions, when Leigh stayed shut in her room for whole days and saw no one, the Siamese had free access. Olivier would try to come in to talk to her and she would turn him away; the cats could come and go, and the actress would talk to them. Boy in particular slept on the bed through the longest hours of the depressive shutdown. What modern psychiatry would call an emotional support animal, though the clinical label did not yet exist, fit that exact role for Leigh.

The bond with Boy probably ran until the late 1950s. The exact date of the Siamese's death does not appear in the biographies. Leigh kept Siamese cats until her own death from tuberculosis in July 1967, in the Eaton Square apartment in London where she lived after her second divorce. The last cats of her life (Poo Jones is the most mentioned, a seal point present in her final years) inherited the role Boy had opened two decades earlier.

Boy belongs to a small but real category in film history: the working animal who shaped a star's craft from the sidelines. He did not appear on screen. He held a corner of the set, kept a routine, and gave Vivien Leigh a thread of ordinary life to hold while she played a woman losing hers. The cushion in the chair did its job, and Blanche DuBois came home to Notley Abbey under another name.
