Richard III is a 1955 British Technicolor film adaptation of William Shakespeare's historical play of the same name, also incorporating elements from his "Henry VI, Part 3".
 It was directed and produced by Sir Laurence Olivier, who also played the lead role.
 The cast includes many noted Shakespearean actors, including a quartet of knights.
 The film depicts Richard plotting and conspiring to grasp the throne from his brother King Edward IV, played by Sir Cedric Hardwicke.
 In the process, many are killed and betrayed, with Richard's evil leading to his own downfall.
 The prologue of the film states that history without its legends would be "a dry matter indeed", implicitly admitting to the artistic licence that Shakespeare applied to the events of the time.
Richard III (2 October 1452 – 22 August 1485) was King of England from 1483 until his death in 1485, at the age of 32, in the Battle of Bosworth Field.
 He was the last king of the House of York and the last of the Plantagenet dynasty.
 His defeat at Bosworth Field, the last decisive battle of the Wars of the Roses, marked the end of the Middle Ages in England.
 He is the subject of the historical play "Richard III" by William Shakespeare.
Alice Holland, Countess of Kent (c. 1350 – 17 March 1416), LG, formerly Lady Alice FitzAlan, was an English noblewoman, a daughter of the 10th Earl of Arundel, and the wife of the 2nd Earl of Kent, the half-brother of King Richard II.
 As the maternal grandmother of Anne Mortimer, she was an ancestor of King Edward IV and King Richard III, as well as King Henry VII and the Tudor dynasty through her daughter Margaret Holland.
 She was also the maternal grandmother of Joan Beaufort, Queen of Scotland.
An Age of Kings is a fifteen-part serial adaptation of the eight sequential history plays of William Shakespeare ("Richard II", "1 Henry IV", "2 Henry IV", "Henry V", "1 Henry VI", "2 Henry VI", "3 Henry VI" and "Richard III"), produced by the BBC in 1960.
 At the time, the show was the most ambitious Shakespearean television adaptation ever made, and was a critical and commercial success in both the UK and North America.
The Richard III Experience at Monk Bar (formerly known as the "Richard III Museum"), is located in the tallest of the four gatehouses, Monk Bar, in the historical city walls of York, England.
 It describes the life of Richard III, the last king of the Plantagenet dynasty.
Ricardians are people interested in altering the posthumous reputation of Richard III, King of England (reigned 1483–1485).
 Richard III has long been portrayed unfavourably, most notably in William Shakespeare's play "Richard III", in which Richard is portrayed as having murdered his nephew, the crown prince of England, a 12 year old child at the time, in order to secure the English throne for himself.
 Ricardians have worked in an effort to turn this around and to paint this portrayal, and the many other related assertions that followed, as most probably false politically motivated accusations.
The play was never printed in its historical era (in fact, not until 1844); but it survives in nine manuscripts, and is thought to have been well known in its time.
 Scholars have studied the relationships between "Richardus Tertius" and the later plays about Richard III, the anonymous play "The True Tragedy of Richard III" (printed 1594) and Shakespeare's "Richard III".
 In one view, the unknown author of "The True Tragedy" used Legge's play occasionally as a source, but Shakespeare did not.
The True Tragedy of Richard III is an anonymous Elizabethan history play on the subject of Richard III of England.
 It has attracted the attention of scholars of English Renaissance drama principally for the question of its relationship with Shakespeare's "Richard III".
Richard III is a historical play by William Shakespeare believed to have been written in approximately 1592.
 It depicts the Machiavellian rise to power and subsequent short reign of King Richard III of England.
 The play is grouped among the histories in the First Folio and is most often classified as such.
 Occasionally, however, as in the quarto edition, it is termed a tragedy.
 "Richard III" concludes Shakespeare's first tetralogy (also containing "Henry VI" parts 1–3).
Sir James Tyrrell (c. 1455 – 6 May 1502) was an English knight, a trusted servant of King Richard III of England.
 He is known for allegedly confessing to the murders of the Princes in the Tower under Richard's orders.
 William Shakespeare portrays Tyrrell as the man who organises the princes' murder in "Richard III".
