Born in London on September 6, 1972, and raised in the Hackney borough of that city (in the northeast quadrant), Elba pursued acting as a high school student at the behest of a drama teacher. Although his film, television, and stage work officially commenced around 1992, Elba's premiere credited role arrived in 1995, with a supporting role on the episode of the farcical British series Absolutely Fabulous, entitled "Sex." Many supporting roles on British television followed, including such series as Bramwell, The Bill, Degrees of Error, The Ruth Rendell Mysteries, and The Governor.
Elba 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. A couple of years of inactivity ensued, but after a supporting turn on a 2001 episode of Law & Order, Elba landed a starring role on a 2002 HBO cop drama The Wire.
In that part -- Elba's best-known and highest-profiled to date -- he plays pusher "Stringer" Bell, the second in command to drug-dealing kingpin Avon Barksdale (Wood Harris). Elba immediately became notorious for daring to impart a pronounced level of affability to Stringer (despite the character's profession); as a result, the role attained widespread popularity with viewers and helped put the series on the map. Elba stayed on the series through its first three seasons.
