Adewale will play Emeka, a mysterious man whose presence on the island - and intentions - will be revealed in one of the early episodes in the upcoming second season.

Born in London, England, Adewale Akinnuoye-Agbaje split his time as a youth between the U.K. and Nigeria. After earning a Masters in Law from the University of London, a career in acting came his way when acclaimed director Frank Marshall cast him in "Congo." This led to appearances in the films "Ace Ventura: When Nature Calls" and "Legionnaire," the HBO movie "Deadly Voyage," and television series "Cracker" and "New York Undercover," as well as the miniseries "20,000 Leagues Under the Sea." Adewale's dramatic portrayal of the murderous drug addicted prisoner Adebisi in the series "Oz" earned him two NAACP Award nominations. He went on to star opposite Brendan Frasier in "The Mummy Returns" and with Matt Damon in "The Bourne Identity." He recently wrapped production on the film "Get Rich or Die Tryin," opposite Curtis "50 Cent" Jackson, and completed work on the movie "Mistress of Spices," a romantic comedy in which he stars opposite Aishwarya Rai.

"Lost" stars Adewale Akinnuoye-Agbaje as Emeka, Naveen Andrews as Sayid, Emilie de Ravin as Claire, Matthew Fox as Jack, Jorge Garcia as Hurley, Maggie Grace as Shannon, Josh Holloway as Sawyer, Malcolm David Kelley as Walt, Daniel Dae Kim as Jin, Yunjin Kim as Sun, Evangeline Lilly as Kate, Dominic Monaghan as Charlie, Terry O'Quinn as Locke, Harold Perrineau as Michael and Michelle Rodriguez as Ana-Lucia.

J.J. Abrams and Damon Lindelof co-created "Lost" and also serve as executive producers, along with Carlton Cuse, Bryan Burk and Jack Bender. "Lost," which is filmed entirely on location in Hawaii, is from Touchstone Television.
