Charlie Chaplin, Mary Pickford, Douglas Fairbanks, and D. W. Griffith launch United Artists.

United Artists Corporation (UA), currently doing business as United Artists Digital Studios, is an American digital production company. Founded in 1919 by D. W. Griffith, Charlie Chaplin, Mary Pickford, and Douglas Fairbanks, the studio was premised on allowing actors to control their own interests, rather than being dependent upon commercial studios. UA was repeatedly bought, sold, and restructured over the ensuing century. Metro-Goldwyn-Mayer acquired the studio in 1981 for a reported $350 million ($1 billion today).On September 22, 2014, MGM acquired a controlling interest in entertainment companies One Three Media and Lightworkers Media, then merged them to revive United Artists' television production unit as United Artists Media Group (UAMG). However, on December 14 of the following year, MGM wholly acquired UAMG and folded it into MGM Television.United Artists was again revived in 2018 as United Artists Digital Studios. Mirror, the joint distribution venture between MGM and Annapurna Pictures, was subsequently rebranded as United Artists Releasing in early February 2019, in honor of its 100th anniversary.

Sir Charles Spencer Chaplin Jr. (16 April 1889 – 25 December 1977) was an English comic actor, filmmaker, and composer who rose to fame in the era of silent film. He became a worldwide icon through his screen persona, the Tramp, and is considered one of the film industry's most important figures. His career spanned more than 75 years, from childhood in the Victorian era until a year before his death in 1977, and encompassed both adulation and controversy.

Chaplin's childhood in London was one of poverty and hardship. His father was absent and his mother struggled financially - he was sent to a workhouse twice before age nine. When he was 14, his mother was committed to a mental asylum. Chaplin began performing at an early age, touring music halls and later working as a stage actor and comedian. At 19, he was signed to the Fred Karno company, which took him to America. He was scouted for the film industry and began appearing in 1914 for Keystone Studios. He soon developed the Tramp persona and attracted a large fan base. He directed his own films and continued to hone his craft as he moved to the Essanay, Mutual, and First National corporations. By 1918, he was one of the world's best-known figures.

In 1919, Chaplin co-founded distribution company United Artists, which gave him complete control over his films. His first feature-length film was The Kid (1921), followed by A Woman of Paris (1923), The Gold Rush (1925), and The Circus (1928). He initially refused to move to sound films in the 1930s, instead producing City Lights (1931) and Modern Times (1936) without dialogue. His first sound film was The Great Dictator (1940), which satirised Adolf Hitler. The 1940s were marked with controversy for Chaplin, and his popularity declined rapidly. He was accused of communist sympathies, and some members of the press and public were scandalized by his involvement in a paternity suit and marriages to much younger women. An FBI investigation was opened, and Chaplin was forced to leave the United States and settle in Switzerland. He abandoned the Tramp in his later films, which include Monsieur Verdoux (1947), Limelight (1952), A King in New York (1957), and A Countess from Hong Kong (1967).

Chaplin wrote, directed, produced, edited, starred in, and composed the music for most of his films. He was a perfectionist, and his financial independence enabled him to spend years on the development and production of a picture. His films are characterised by slapstick combined with pathos, typified in the Tramp's struggles against adversity. Many contain social and political themes, as well as autobiographical elements. He received an Honorary Academy Award for "the incalculable effect he has had in making motion pictures the art form of this century" in 1972, as part of a renewed appreciation for his work. He continues to be held in high regard, with The Gold Rush, City Lights, Modern Times, and The Great Dictator often ranked on lists of the greatest films.
