Chiwetel Ejiofor is a British actor, director and writer most popular for playing the role of Dr. Adrian Helmsley in the 2009 Disaster Film 2012.
Ejiofor made his film debut in the television film Deadly Voyage in 1996. He went on to become a stage actor in London. In Steven Spielberg's Amistad, he gave support to Djimon Hounsou's Cinque as interpreter Ens. James Covey.
Ejiofor had his first leading film role in 2002's Dirty Pretty Things, for which he won a British Independent Film Award for best actor.
Ejiofor appeared alongside John Cusack in the 2009 film 2012, with a role which he played a scientist discovering shocking details about the end of the world.
In 2013, Ejiofor took on one of his most notable roles to date, Solomon Northup in 12 Years a Slave. The film was based on Northup's memoir, edited in 1968 by historians Sue Eakin and Joseph Logsdon, of Northup's experience as a free black man in New York, who was kidnapped in 1841 and sold into slavery in Louisiana. On casting, director Steve McQueen said: "Chiwetel Ejiofor was always going to be Solomon Northup for me. I was looking for someone that had that genteelness, that kind of humanity. Knowing that humanity was going to be tested under certain duress and circumstances, I needed a person who could actually keep hold of that, even through periods of extraordinary trying and extraordinary situations where it would be tested to its absolute limit. He was the only person.” At the Toronto International Film Festival, Ejiofor said he briefly hesitated about playing Northup. "You wait all your life for a great script to come through the door. You're hassling your agent and all that, and then it comes and you read it and your first reaction surprises you. Your first reaction being, 'Can I do this?'" He accepted the role about 24 hours later. As part of his preparation, Ejiofor learned to play the violin, collected slave stories, maintained a slave's edge up hairstyle, and engaged in some of the physical labour that Northup did like picking cotton.
