Sir David Mark Rylance Waters (born 18 January 1960) is an English actor, theatre director, and playwright.
 He was the first artistic director of Shakespeare's Globe in London, from 1995 to 2005.
 His film appearances include "Prospero's Books" (1991), "Angels and Insects" (1995), "Institute Benjamenta" (1996), and "Intimacy" (2001).
 Rylance won the Academy Award and the BAFTA Award for Best Supporting Actor for his portrayal of Rudolf Abel in "Bridge of Spies" (2015).
Rudolf Ivanovich Abel (Russian: Рудольф Иванович Абель ), real name Vilyam "Willie" Genrikhovich Fisher (Вильям "Вилли" Генрихович Фишер), (July 11, 1903 – November 15, 1971) was a Soviet intelligence officer.
 He adopted his alias when arrested on charges of conspiracy by FBI agents in 1957.
24-7 Spyz (pronounced "twenty-four-seven spies") are a band from the South Bronx, New York, formed in 1986, originally consisting of Jimi Hazel (real name, Wayne K. Richardson) (guitar), Rick Skatore (real name, Kenneth D. Lucas) (bass), Kindu Phibes (drums), and P. Fluid (real name, Peter Forrest) (vocals).
 The band is best known for mixing soul, funk, reggae, and R&B with heavy metal and hardcore punk.
 The fact that they are African Americans playing variations of heavy metal led critics to compare them to bands such as Living Colour and Bad Brains.
 Though they were pioneers in the fusion of these particular music styles, influencing many bands, they have never achieved substantial commercial success.
 After several lineup changes, the band broke up in 1998, but reformed in 2003 before releasing their first new album of original material in over a decade in 2006.
 As of October 2014, the lineup of the band includes Jimi Hazel, Rick Skatore, drummer Phillip "Fish" Fisher and guitarist Ronny Drayton.
The Declaration of Reasonable Doubt is an Internet signing petition which seeks to enlist broad public support for the Shakespeare authorship question to be accepted as a legitimate field of academic inquiry.

 As of 23 April 2016, the 400th anniversary of Shakespeare's death the document had been signed by 3,348 people, including 573 self-described current and former academics.
