The year 1917 in film involved some significant events.

U.S.A. unless stated

Theda Bara ( /ˈθiːdə ˈbærə/THEE-də BAR-ə; July 29, 1885 – April 7, 1955), born Theodosia Burr Goodman, was an American silent film actress – one of the most popular of her era, and one of cinema's earliest sex symbols. Her femme fatale roles earned her the nickname "The Vamp" (short for vampire).

Theodosia Burr Goodman was born in the Avondale section of Cincinnati, Ohio. Her father was Bernard Goodman (1853–1936), a prosperous Jewish tailor born in Poland. Her mother, Pauline Louise de Coppett (1861–1957), was born in Switzerland. Bernard and Pauline married in 1882.

Theda's siblings were a boy, Marque (1888–1954) and a girl, Esther (1897–1965), who also became a film actress as Lori Bara and married Francis W. Getty of London in 1920.

The origin of Bara's stage name is disputed; The Guinness Book of Movie Facts and Feats says it came from director Frank Powell, who learned Theda had a relative named Barranger. In promoting the 1917 film "Cleopatra", Fox Studio publicists noted that the name was an anagram of "Arab death", and her press agents claimed inaccurately that she was "the daughter of an Arab sheik and a French woman, born in the Sahara."

Robert Charles Durman Mitchum (August 6, 1917 – July 1, 1997) was an American film actor, author, composer and singer and is #23 on the American Film Institute's list of the greatest male American screen legends of all time. Mitchum rose to prominence for his starring roles in several major works of the film noir style, and is considered a forerunner of the anti-heroes prevalent in film during the 1950s and 1960s.

Mitchum was born in Bridgeport, Connecticut, into a Methodist family. His mother, Ann Harriet (née Gunderson), was a Norwegian immigrant and sea captain's daughter, and his father, James Thomas Mitchum, was a shipyard and railroad worker. A sister, Annette, (known as Julie Mitchum during her acting career) was born in 1914. James Mitchum was crushed to death in a railyard accident in Charleston, South Carolina, in February 1919, when his son was less than 2 years old. After his death, Ann Mitchum was awarded a government pension, and soon realized she was pregnant. She returned to her family in Connecticut, and married a former British Army major who helped her care for the children. In September 1919 a second son, John, was born. When all of the children were old enough to attend school, Ann found employment as a linotype operator for the Bridgeport Post.

Samuel Langhorne Clemens (November 30, 1835 – April 21, 1910), better known by his pen name Mark Twain, was an American author and humorist. He is most noted for his novels, The Adventures of Tom Sawyer (1876), and its sequel, Adventures of Huckleberry Finn (1885), the latter often called "the Great American Novel."

Twain grew up in Hannibal, Missouri, which would later provide the setting for Huckleberry Finn and Tom Sawyer. He apprenticed with a printer. He also worked as a typesetter and contributed articles to his older brother Orion's newspaper. After toiling as a printer in various cities, he became a master riverboat pilot on the Mississippi River, before heading west to join Orion. He was a failure at gold mining, so he next turned to journalism. While a reporter, he wrote a humorous story, "The Celebrated Jumping Frog of Calaveras County", which became very popular and brought nationwide attention. His travelogues were also well-received. Twain had found his calling.

He achieved great success as a writer and public speaker. His wit and satire earned praise from critics and peers, and he was a friend to presidents, artists, industrialists, and European royalty.

Sir Charles Spencer "Charlie" Chaplin, KBE (16 April 1889 – 25 December 1977) was an English comic actor, film director and composer best known for his work during the silent film era. He became the most famous film star in the world before the end of World War I. Chaplin used mime, slapstick and other visual comedy routines, and continued well into the era of the talkies, though his films decreased in frequency from the end of the 1920s. His most famous role was that of The Tramp, which he first played in the Keystone comedy Kid Auto Races at Venice in 1914. From the April 1914 one-reeler Twenty Minutes of Love onwards he was writing and directing most of his films, by 1916 he was also producing them, and from 1918 he was even composing the music for them. With Mary Pickford, Douglas Fairbanks and D. W. Griffith, he co-founded United Artists in 1919.

Chaplin was one of the most creative and influential personalities of the silent-film era. He was influenced by his predecessor, the French silent film comedian Max Linder, to whom he dedicated one of his films. His working life in entertainment spanned over 75 years, from the Victorian stage and the music hall in the United Kingdom as a child performer, until close to his death at the age of 88. His high-profile public and private life encompassed both adulation and controversy. Chaplin was identified with left-wing politics during the McCarthy era and he was ultimately forced to resettle in Europe from 1952.
