Trivia: Born in London on September 6, 1972, and raised in the Hackney borough, Elba pursued acting as a high school student at the behest of a drama teacher. Elba paid his dues with many supporting roles on British television, including such series as Bramwell, The Bill, Degrees of Error, The Ruth Rendell Mysteries, and The Governor. The actor grew deeply frustrated, however, over the seemingly irrepressible tendency of British casting directors to peg him in supporting roles. "Back in London," he later recalled, "I was always just going to be the best friend, or the crook or the detective on the side." When Elba could take no more of this, he immigrated to the United States. Within a few years, Elba landed a starring role on what would come to be known as one of the best TV series of all time, The Wire.Elba's performance as pusher "Stringer" Bell attained widespread popularity with viewers and helped put Elba on the map. Elba then transitioned into big-screen roles in movies like The Gospel, The Reaping, Tyler Perry's Daddy's Little Girls, 28 Weeks Later, and the Alien prequel Prometheus. Elba also enjoyed more stateside TV success on shows like The Office and Luther.

Trivia: Born Patrick G. Duggan on March 24, 1945, Patrick Malahide grew up in the Thames Valley west of London in the village of Pangbourne, where Kenneth Grahame wrote about Mole, Toad, and Rat in the 1908 children's classic The Wind in the Willows. Malahide's Irish immigrant parents each held down two jobs to send Patrick and their other two children to the best schools. Patrick attended St. Anne's Primary and then the Douai School of the Benedictine Abbey at Upper Woolhampton, Berkshire. At both schools, Patrick received an excellent education and learned to mix with upper-class children and mimic the articulation and cadence of their speech. Thus, he was unwittingly preparing himself for film roles requiring an understanding of class-conscious societies and a mastery of accents. Such roles included his portrayal of Sir John Conroy in the 2001 TV miniseries Victoria and Albert, Captain Claude Howlett in the 1999 TV miniseries All the King's Men, and the Rev. Casaubon in the 1994 TV miniseries Middlemarch. After attending Edinburgh University, where he studied literature and psychology and performed with a dramatic society, he taught English at a boys' school in Wokingham. Soon, however, he abandoned the classroom for the stage, managing and directing at a small theater and acting in the plays of Henrik Ibsen, Noel Coward, Anton Chekhov, and Arthur Miller. After performing in London, he signed on with the Royal Lyceum Theatre in Edinburgh, playing roles in the dramas of Shakespeare and other classic authors, accepted television roles, and earned critical acclaim in 1981 in a tour de force one-man show, Judgement [writer's note: the British spelling of the word "judgment" is correct here], in which he tells the audience why he resorted to cannibalism to survive as a Russian officer in a Nazi prison. Then came worldwide recognition from productions such as The Killing Fields (1984), the TV miniseries The Singing Detective (1985), A Month in the Country (1987), the TV docudrama Investigation: Inside a Terrorist Bombing (1990), A Man of No Importance (1994), U.S. Marshals (1998), and Billy Elliot (2000).
