Charles Laughton (1 July 1899 – 15 December 1962) was an English stage and film actor, director, producer and screenwriter.
 Laughton was trained in London at the Royal Academy of Dramatic Art and first appeared professionally on the stage in 1926.
 In 1927, he was cast in a play with his future wife Elsa Lanchester, with whom he lived and worked until his death; they had no children.
The Private Life of the Gannets is a 1934 British short documentary film, directed by Julian Huxley, about a colony of Northern Gannet (Morus bassanus) on the small rocky island of Grassholm, off the coast of Wales.
 It received a special mention at the 3rd Venice International Film Festival in 1935 and won the Best Short Subject (One-Reel) at the 10th Academy Awards in 1938.
 The title was chosen by producer Alexander Korda as a reference to "The Private Life of Henry VIII" (1933), his breakthrough film of the previous year.
Bartolommeo Penni was a Florentine High Renaissance painter active in the 16th century, the brother of the painters Luca Penni and Gianfrancesco Penni - the three brothers originally came from a family of weavers.
 Bartolommeo moved to England with "Antony Toto" (Antonio di Nunziato d'Antonio) and served as a court artist to Henry VIII of England between 1531 and 1533.
 He probably came to Henry from Cardinal Wolsey, as he and Toto first appear in the accounts just after Wolsey's fall in October 1529.
 "Toto" had been signed on in Florence in 1519 as an assistant to Pietro Torrigiano, who in fact left England for good later that year.
 Toto and Penni spent most of their time after 1538 working on Nonsuch Palace, including elaborate stucco work for Henry's most advanced building, now vanished.
 Penni is recorded as still in England in 1538 and also worked as painter-decorator to Henry's son and successor Edward VI of England.
The Private Life of Louis XIV or Liselotte of the Palatinate (German:Liselotte von der Pfalz) is a 1935 German historical film directed by Carl Froelich and starring Renate Müller, Eugen Klöpfer and Maria Krahn.
 The film's English language release title is a reference to the hit British film "The Private Life of Henry VIII" (1933).
Henry VIII and His Six Wives is a four-part British documentary first broadcast in 2016 about Henry VIII and his wives, chronicling his turbulent private life and how it shaped Britain.
The Private Life of Henry VIII is a 1933 British film, directed and co-produced by Alexander Korda and starring Charles Laughton, Robert Donat, Merle Oberon and Elsa Lanchester.
 The film focuses on the marriages of King Henry VIII of England.
 It was written by Lajos Bíró and Arthur Wimperis for London Film Productions, Korda's production company.
 The film was a major international success, establishing Korda as a leading filmmaker and Laughton as a box office star.
Henry VIII is a collaborative history play, written by William Shakespeare and John Fletcher, based on the life of King Henry VIII of England.
 An alternative title, All Is True, is recorded in contemporary documents, the title Henry VIII not appearing until the play's publication in the First Folio of 1623.
 Stylistic evidence indicates that individual scenes were written by either Shakespeare or his collaborator and successor, John Fletcher.
 It is also somewhat characteristic of the late romances in its structure.
 It is noted for having more stage directions than any of Shakespeare's other plays.
The Public Life of Henry the Ninth is a 1935 British comedy film directed by Bernard Mainwaring and starring Leonard Henry, Betty Frankiss, and George Mozart.
 This film was the first film made by Hammer Productions, and was Henry's film debut.
 It is set largely in the bar of the Henry VIII public house, with the title alluding to the 1933 Oscar-winning film "The Private Life of Henry VIII".
Young Bess is a 1953 Technicolor biographical film made by Metro-Goldwyn-Mayer about the early life of Elizabeth I, from her turbulent childhood to the eve of her accession to the throne of England.
 The film starred Jean Simmons and Stewart Granger as Thomas Seymour, with Charles Laughton as Elizabeth's father, Henry VIII, a part he had played twenty years before in "The Private Life of Henry VIII".
 The film was directed by George Sidney and produced by Sidney Franklin, from a screenplay by and Arthur Wimperis based on the novel by Margaret Irwin (1944).
