An epic story of abiding faith and uncommon courage.

It is the true story of a reluctant leader called to do the impossible and the loyal friends who risk everything to join him.

Amazing Grace is based on the true story of William Wilberforce, a British statesman and reformer from the early part of the 19th century. He was also instrumental in passing legislation to abolish slavery in the British colonies, a victory he won just three days before his death in 1833.

The film stars Ioan Gruffudd (Black Hawk Down), Albert Finney (Erin Brockovich), Romola Garai (Vanity Fair), Michael Gambon (Harry Potter and the Prisoner of Azkaban), Benedict Cumberbatch (Hawking), Rufus Sewell (Legend of Zorro), Ciaran Hinds (Rome) and introduces Youssou N'Dour.

Gruffudd plays Wilberforce, who, as a Member of Parliament, navigated the world of 18th Century backroom politics to end the slave trade in the British Empire. Albert Finney plays John Newton, a confidante of Wilberforce who inspires him to pursue a life of service to humanity. Benedict Cumberbatch is William Pitt the Younger, England's youngest ever Prime Minister at the age of 24, who encourages his friend Wilberforce to take up the fight to outlaw slavery and supports him in his struggles in Parliament.

Elected to the House of Commons at the age of 21, and on his way to a successful political career, Wilberforce, over the course of two decades, took on the English establishment and persuaded those in power to end the inhumane trade of slavery.

Romola Garai plays Barbara Spooner, a beautiful and headstrong young woman who shares Wilberforce's passion for reform, and who becomes his wife after a whirlwind courtship. Youssou N'Dour is Olaudah Equiano. Born in Africa and sent as a slave to the Colonies, Equiano bought his freedom and made his home in London, where he wrote a best-selling account of his life and became a leading figure in the fight to end the slavery of his fellow countrymen.
