Has a masters in Law from the University of London, but took a different career path when bitten by the acting bug.
Is perhaps best known for his role as the cunning, fierce super-criminal Adebisi on Oz (1997). Another role he is very much associated with is the enigmatic 'Mr. Eko' from Lost (2004), even though he played that role in only 28 of the series' 117 episodes.
He went from playing Ernie Hudson's good friend, the guide "Kahega" to Hudson's "Capt. Munro" in Congo (1995), to playing his enemy, the sociopath "Adebisi" to Hudson's hard-headed "Warden Glynn" in Oz (1997).
The son of immigrants from Nigeria, he has played almost entirely African characters despite having been born and raised in England. He usually employs a deep, Nigerian timber while acting, while off-screen he has a very British, somewhat Cockney accent.
He is fluent in several languages including Italian, Yoruba, Swahili, and (of course) English. He can "get along" in a few other languages, including French.
He is a Buddhist and admitted that he had to chant more than usual while playing the brutal character of "Majestic" in Get Rich or Die Tryin' (2005).
Had a successful career as a model in Milan and Paris, before pursuing acting.
The name of his character, "Atticus" in the action adventure film Pompeii is similar to a role he played in the 20,000 Leagues Under the Sea TV film, the name of whom was "Cabe Attucks".
The woolly hat he wore as Simon Adebisi in ''Oz (1997-2003)'' was his idea and based on hats he'd seen gang members wear growing up in London.
Appears in both the Marvel Cinematic Universe and the DC Cinematic Universe with roles in Thor: The Dark World and Suicide Squad.
Full name is pronounced like a-de-wall-e a-key-new-ye ag-ba-he.
