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 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).
