<human>: Dame Angela Brigid Lansbury  (born 16 October 1925) is an English-American-Irish actress who has appeared in theatre, television, and film, as well as a producer and singer. Her career has spanned seven decades, much of it in the United States, and her work has attracted international acclaim. Lansbury was born to an upper-middle-class family in Regents Park, central London, the daughter of Irish actress Moyna Macgill and English politician Edgar Lansbury. To escape the Blitz, in 1940 she moved to the United States with her mother and two younger brothers, and studied acting in New York City.

Lansbury was born to an upper middle class family on October 16, 1925. Although her birthplace has often been given as Poplar, East London, she has rejected this, asserting that while she had ancestral connections to Poplar, she was born in Regent's Park, Central London. Her mother was Belfast-born actress Moyna Macgill (born Charlotte Lillian McIldowie), who regularly appeared on stage in the West End and who had also starred in several films. Her father was the wealthy English timber merchant and politician Edgar Lansbury, a member of the Communist Party of Great Britain and former mayor of the Metropolitan Borough of Poplar. Her paternal grandfather was the Labour Party leader and anti-war activist George Lansbury, a man whom she felt "awed" by and considered "a giant in my youth." Angela had an older half sister, Isolde, who was the offspring of Moyna's previous marriage to writer and director Reginald Denham. In January 1930, when Angela was four, her mother gave birth to twin boys, Bruce and Edgar, leading the Lansburys to move from their Poplar flat to a house in Mill Hill, North London; on weekends they would vacate to a rural farm in Berrick Salome, near Wallingford, Oxfordshire.  When Lansbury was nine, her father died from stomach cancer; she retreated into playing characters as a coping mechanism.  In 2014, Lansbury described this event as "the defining moment of my life. Nothing before or since has affected me so deeply." Facing financial difficulty, her mother became engaged to a Scottish colonel, Leckie Forbes, and moved into his house in Hampstead, with Lansbury receiving an education at South Hampstead High School from 1934 until 1939. She nevertheless considered herself largely self-educated, learning from books, theatre and cinema. She became a self-professed "complete movie maniac", visiting the cinema regularly and imagining herself as certain characters. Keen on playing the piano, she briefly studied music at the Ritman School of Dancing, and in 1940 began studying acting at the Webber Douglas School of Singing and Dramatic Art in Kensington, West London, first appearing onstage as a lady-in-waiting in the school's production of Maxwell Anderson's Mary of Scotland.  That year, Angela's grandfather died, and with the onset of the Blitz, Macgill decided to take Angela, Bruce and Edgar to the United States; Isolde remained in Britain with her new husband, the actor Peter Ustinov. Macgill secured a job supervising sixty British children who were being evacuated to North America aboard the Duchess of Athol, arriving with them in Montreal, Quebec, Canada, in mid-August. From there, she proceeded by train to New York City, where she was financially sponsored by a Wall Street businessman, Charles T. Smith, moving in with his family at their home at Mahopac, New York. Lansbury gained a scholarship from the American Theatre Wing allowing her to study at the Feagin School of Drama and Radio, where she appeared in performances of William Congreve's The Way of the World and Oscar Wilde's Lady Windermere's Fan. She graduated in March 1942, by which time the family had moved to a flat in Morton Street, Greenwich Village.  Macgill secured work in a Canadian touring production of Tonight at 8:30, and was joined in Canada by her daughter, who gained her first theatrical job as a nightclub act at the Samovar Club, Montreal. Having gained the job by claiming to be 19 when she was 16, her act consisted of her singing songs by Noel Coward, and earned her $60 a week. She returned to New York City in August 1942, but her mother had moved to Hollywood, Los Angeles, in order to resurrect her cinematic career; Lansbury and her brothers followed. Moving into a bungalow in Laurel Canyon, both Lansbury and her mother obtained Christmas jobs at the Bullocks Wilshire department store in Los Angeles; Moyna was sacked for incompetence, leaving the family to subsist on Lansbury's wages of $28 a week. Befriending a group of gay men, Lansbury became privy to the city's underground gay scene, and with her mother, attended lectures by the spiritual guru Krishnamurti; at one of these, she met Aldous Huxley.  At a party hosted by her mother, Lansbury met John van Druten, who had recently co-authored a script for Gaslight (1944), a mystery-thriller based on Patrick Hamilton's 1938 play, Gas Light. Set in Victorian London, the film was being directed by George Cukor, and starred Ingrid Bergman in the lead role of Paula Alquist, a woman being psychologically tormented by her husband. Van Druten suggested that Lansbury would be perfect for the role of Nancy Oliver, a conniving cockney maid; she was accepted for the part, although, since she was only 17, a social worker had to accompany her on the set. Obtaining an agent, Earl Kramer, she was signed to a seven-year contract with MGM, earning $500 a week and using her real name as her professional name. Upon release, Gaslight received mixed critical reviews, although Lansbury's role was widely praised; the film earned six Academy Award nominations, including one for Best Supporting Actress for Lansbury.  Her next film appearance was as Edwina Brown, the older sister of Velvet Brown in National Velvet (1944); the film proved to be a major commercial hit, with Lansbury developing a lifelong friendship with co-star Elizabeth Taylor. Lansbury next starred in The Picture of Dorian Gray (1945), a cinematic adaptation of Oscar Wilde's 1890 novel of the same name, which was again set in Victorian London. Directed by Albert Lewin, Lansbury was cast as Sibyl Vane, a working class music hall singer who falls in love with the protagonist, Dorian Gray (Hurd Hatfield). Although the film was not a financial success, Lansbury's performance once more drew praise, earning her a Golden Globe Award, and she was again nominated for Best Supporting Actress at the Academy Awards, losing to Anne Revere, her co-star in National Velvet.  On September 27, 1945, Lansbury married Richard Cromwell, an artist and decorator whose acting career had come to a standstill. Their marriage was troubled; Cromwell was gay, and had married Lansbury in the unsuccessful hope that it would turn him heterosexual. The marriage ended in less than a year when she filed for divorce on September 11, 1946, but they remained friends until his death. In December 1946, she was introduced to fellow English expatriate Peter Pullen Shaw at a party held by former co-star Hurd Hatfield in Ojai Valley. Shaw was an aspiring actor, also signed to MGM, and had recently left a relationship with Joan Crawford. He and Lansbury became a couple, living together before she proposed marriage.  The couple were intent on getting married back in Britain, but the Church of England refused to marry two divorcees. Instead, they wed at St. Columba's Church, a place of worship under the jurisdiction of the Church of Scotland, in Knightsbridge, London in August 1949, followed by a honeymoon in France. Returning to the U.S., where they settled into Lansbury's home in Rustic Canyon, Malibu, in 1951 both became naturalised U.S. citizens, albeit retaining their British citizenship via dual nationality.  Following the success of Gaslight and The Picture of Dorian Gray, MGM cast Lansbury in eleven further films until her contract with the company ended in 1952. Keeping her among their B-list stars, MGM used her less than their similar-aged actresses; biographers Edelman and Kupferberg believed that the majority of these films were "mediocre", doing little to further her career. This view was echoed by Cukor, who believed Lansbury had been "consistently miscast" by MGM. She was repeatedly made to portray older women, often villainous, and as a result became increasingly dissatisfied with working for MGM, commenting that "I kept wanting to play the Jean Arthur roles, and Mr Mayer kept casting me as a series of venal bitches." The company themselves were suffering from the post-1948 slump in cinema sales, as a result slashing film budgets and cutting their number of staff.  1946 saw Lansbury play her first American character as "Em", a tough honky-tonk saloon singer who slaps Judy Garland's character in the Oscar-winning Wild West musical The Harvey Girls. She appeared in The Hoodlum Saint (1946), Till the Clouds Roll By (1947), If Winter Comes (1947), Tenth Avenue Angel (1948), The Three Musketeers (1948), State of the Union (1948) and The Red Danube (1949). She was loaned by MGM first to United Artists for The Private Affairs of Bel Ami (1947), and then to Paramount for Samson and Delilah (1949). She appeared as a villainous maidservant in Kind Lady (1951) and a French adventuress in Mutiny (1952). Turning to radio, in 1948 she appeared in an audio adaptation of Somerset Maugham's Of Human Bondage for NBC University Theatre and the following year she starred in their adaptation of Jane Austen's Pride and Prejudice. Moving into television, she appeared in a 1950 episode of Robert Montgomery Presents adapted from A.J. Cronin's The Citadel. CANNOTANSWER
