Sir Cedric Webster Hardwicke (19 February 1893 – 6 August 1964) was a noted English stage and film actor whose career spanned nearly fifty years. Hardwicke's theatre work included notable performances in productions of the plays of William Shakespeare and George Bernard Shaw, and his film work included leading roles in a number of adapted literary classics.

Hardwicke was born in Lye, Worcestershire, the son of Jessie (née Masterson) and her husband Dr. Edwin Webster Hardwicke. He attended Bridgnorth Grammar School in Shropshire and then trained at the Royal Academy of Dramatic Art (RADA).

In 1928, he married English actress Helena Pickard. Hardwicke's son was the actor Edward Hardwicke, a well-known television actor in the UK.

He made his first appearance on stage at London's Lyceum Theatre in 1912 during the run of Frederick Melville's melodrama The Monk and the Woman, when he took up the part of Brother John. During that year he was at Her Majesty's Theatre understudying, and subsequently appeared at the Garrick Theatre in Charles Klein's play Find the Woman, and Trust the People. In 1913 he joined Benson's Company and toured in the provinces, South Africa, and Rhodesia. During 1914 he toured with Miss Darragh (Letitia Marion Dallas, d. 1917) in Laurence Irving's play The Unwritten Law, and he appeared at the Old Vic in 1914 as Malcolm in Macbeth, Tranio in The Taming of the Shrew, and the gravedigger in Hamlet, among many other roles.

Charles Laughton (1 July 1899 – 15 December 1962) was an English-born American stage and film actor, screenwriter, producer and director.

Laughton was born in Scarborough, North Yorkshire, the son of Robert Laughton and his wife Elizabeth (née Conlon), Yorkshire hotel keepers. His mother was a devout Roman Catholic of Irish descent. He attended Stonyhurst College, a Jesuit school, in Lancashire. He served during World War I (in which he was gassed) first with the 2/1st Battalion of the Huntingdonshire Cyclist Regiment and later with the 7th Battalion of the Northamptonshire Regiment.

King Arthur is a legendary British leader of the late 5th and early 6th centuries, who, according to medieval histories and romances, led the defence of Britain against Saxon invaders in the early 6th century. The details of Arthur's story are mainly composed of folklore and literary invention, and his historical existence is debated and disputed by modern historians. The sparse historical background of Arthur is gleaned from various sources, including the Annales Cambriae, the Historia Brittonum, and the writings of Gildas. Arthur's name also occurs in early poetic sources such as Y Gododdin.

The legendary Arthur developed as a figure of international interest largely through the popularity of Geoffrey of Monmouth's fanciful and imaginative 12th-century Historia Regum Britanniae (History of the Kings of Britain). Some Welsh and Breton tales and poems relating the story of Arthur date from earlier than this work; in these works, Arthur appears either as a great warrior defending Britain from human and supernatural enemies or as a magical figure of folklore, sometimes associated with the Welsh Otherworld, Annwn. How much of Geoffrey's Historia (completed in 1138) was adapted from such earlier sources, rather than invented by Geoffrey himself, is unknown.

Jessie Matthews, OBE (11 March 1907 – 19 August 1981) was an English actress, dancer and singer of the 1930s, whose career continued into the post-war period.

Jessie Margaret Matthews was born in Soho, London, in relative poverty, the seventh of sixteen children (of whom eleven survived) of a fruit-and-vegetable seller. She debuted on stage on 29 December 1919, aged 12, in Bluebell in Fairyland, by Seymour Hicks, music by Walter Slaughter and lyrics by Charles Taylor, at the Metropolitan Music Hall, Edgware Road, London, as a child dancer; she made her film debut in 1923 in the silent film The Beloved Vagabond.

Matthews was in the chorus in Charlot Review in London. She went with the show to New York, where she was also understudy to the star, Gertrude Lawrence. When Lawrence fell ill, she took over the role and was given great reviews. Matthews was acclaimed in the United Kingdom as a dancer and as the first performer of numerous popular songs of the 1920s and 1930s, including "A Room with a View" and London Calling! by Noël Coward and "Let's Do It, Let's Fall in Love" by Cole Porter. After a string of hit stage musicals and films in the mid-1930s, Matthews developed a following in the USA, where she was dubbed "The Dancing Divinity". Her British studio was reluctant to let go of its biggest name, which resulted in offers for her to work in Hollywood being repeatedly rejected.

Ellen Miriam Hopkins (October 18, 1902 – October 9, 1972) was an American actress known for her versatility in a wide variety of roles.

Hopkins was born in Savannah, Georgia, and raised in Bainbridge, near the Alabama border. She attended Goddard Seminary in Barre, Vermont (which later became Goddard College in Plainfield, Vermont) and Syracuse University (in New York), but apparently did not matriculate.

At age 20, Hopkins became a chorus girl in New York City. In 1930, she signed with Paramount Pictures, and made her official film debut in Fast and Loose. Her first great success was in the 1931 horror drama film Dr. Jekyll and Mr. Hyde, in which she portrayed the character Ivy Pearson; a prostitute who becomes entangled with the lead protagonists Jekyll and Hyde. Hopkins received rave reviews, however due to the controversy that surrounded the finished film and in particular, her character, many of Hopkins's scenes were cut before the official release. This reduced Hopkins to approximately five minutes of screen time.
