12 Years A Slave star Chiwetel Ejiofor on his moment

Chiwetel Ejiofor has admitted he was so daunted by the responsibility of playing a free man forced into slavery he waited a "day or two" before agreeing to take the leading role in 12 Years A Slave.

The controversial film tells the true story of Solomon Northup, who was kidnapped and sold into slavery in 1841.

Chiwetel talks about pre-filming nerves with the BBC's arts editor Will Gompertz.
