Stringer Bell was one of the most popular characters on "The Wire" -- a calculating, if easily duped, would-be real estate developer who worked for the Barksdale organization. He was a an enigma of a man who read Adam Smith's "The Wealth of Nations" and also had a penchant for bad ideas like wanting to assassinate a senator who pocketed a $250,000 bribe. Much of the credit for Stringer Bell's believability comes down to English actor Idris Elba, who portrayed Bell for three seasons. Elba, named one of People's 100 Most Beautiful People in 2007, has a career on the rise, with a lead in "Tyler Perry's Daddy's Little Girls," an appearance in "American Gangster" and an a new recurring role as Charles Miner on "The Office." His next project is "Obsessed" a suspense thriller with Beyonce and Ali Larter, which will be released later this month. Elba is in town to do some promotional appearances, and he's hosting the weekly Pandora happy hour at the Park at 14th tonight. There's an open bar from 5 to 6, then happy hour with drinks and snacks from 6 to 8, and DJs Oz and Money spin the hits until 2 a.m. E-mail your full name (and names of your friends, if attending) to firstname.lastname@example.org by 5 p.m. Thursday for free admission before 10.
