Troy is a trilogy of radio plays, first broadcast on BBC Radio 3 from 28 November to 30 November 1998.
 The cast is led by Paul Scofield, who came out of retirement to take part.
 Troy was written by Andrew Rissik and produced by Jeremy Mortimer.
 The trilogy is a companion piece to "King Priam", Rissik's earlier more optimistic take on the story in which Scofield took the title role.
John Clifford, 9th Baron Clifford, (8 April 1435 – 28 March 1461), was a Lancastrian military leader during the Wars of the Roses.
 The Clifford family were one of the most prominent families among the northern English nobility of the fifteenth century; and by the marriages of his sisters John Clifford had links to some very important families of the time, including the earls of Devon.
 He was orphaned at about twenty years of age when his father was slain at the first battle of the Wars of the Roses, the Battle of St Albans in 1455.
 It was probably as a result of his father's death there that John became one of the strongest supporters of Queen Margaret of Anjou, consort of King Henry VI, who ended up as effective leader of the Lancastrian faction.
 John Clifford had already achieved prominence in the north where, as an ally of the son of the earl of Northumberland, he took part in a feud against the Neville family, the Percy's natural rivals in Yorkshire.
 This consisted of a series of armed raids, assaults and skirmishes, and included an ambush on one of the younger Nevilles' wedding party in 1453.
 Historians have seen a direct connection between his involvement in the local feud in the north with the Nevilles, and his involvement in the national struggle against the duke of York, whom the Nevilles were closely allied with in the late 1450s.
 Although this was supposedly a period of temporary peace between the factions, Clifford and his allies appear to have made numerous attempts to ambush the Neville and Yorkist lords.
Sir John Clifford Mortimer, CBE, QC (21 April 1923 – 16 January 2009) was an English barrister, dramatist, screenwriter, and author.
The Pattern of Painful Adventures is a 90-minute 2008 radio play by Stephen Wakelam on the circumstances surrounding the writing of the play "Pericles, Prince of Tyre" by William Shakespeare and the sickness of his brother Edmund's child, introduced by a flashback by his daughter Susannah, playwright John Marston and William's secretary Robinson.
 It links the play to the marriage of Susannah and the birth of her daughter and to the similar themes of daughters, forests, storms, shipwrecks and lost infants from "As You Like It", "The Winter's Tale", and "The Tempest".
 It is named after "The Pattern of Painful Adventures", a main source for "Pericles".
 It was first broadcast on BBC Radio 3 at 8pm on 23 November 2008, directed and produced by Jeremy Mortimer, and was followed in the same slot on 30 November by a repeat of a 2005 radio production of "Pericles", with Tom Mannion as Pericles and Benjamin Zephaniah as Gower.

To Notice Such Things is a studio album by former Deep Purple keyboard player Jon Lord, released in 2010.
 It is titled after the main work, a six-movement suite for solo flute, piano and string orchestra, composed by Lord in memory of his close friend the late Sir John Mortimer, CBE, QC.
 The music emanates from that which Lord composed for the stage show, Mortimer’s Miscellany, which he also occasionally accompanied.
 To Notice Such Things is the last line of the Thomas Hardy poem “Afterwards”, which ended the show.
Match Point is a 2005 British-Luxembourgish psychological thriller film written and directed by Woody Allen and starring Jonathan Rhys Meyers, Scarlett Johansson, Emily Mortimer, Matthew Goode, Brian Cox, and Penelope Wilton.
 In the film, Rhys Meyers's character marries into a wealthy family, but his social position is threatened by his affair with his brother-in-law's girlfriend, played by Johansson.
 The film treats themes of morality, greed, and the roles of lust, money, and luck in life, leading many to compare it to Allen's earlier film "Crimes and Misdemeanors" (1989).
 It was produced and filmed in London after Allen had difficulty finding financial support for the film in New York.
 The agreement obliged him to make it there using a cast and crew mostly from the United Kingdom.
 Allen quickly re-wrote the script, which was originally set in New York, for a British setting.
