Chiwetel Ejiofor in 12 Years a Slave.

12 Years a Slave is based on the true story of Solomon Northup, a free black man living in upstate New York before the Civil War who was abducted and sold into slavery. This latest effort from director Steve McQueen is a towering achievementโ€”one of the yearโ€™s bravest and most-uncompromising films.

Chiwetel Ejiofor is a lock for an Oscar nomination as Northup, who is forced to work on cotton plantations, one of them run by the despicable Edwin Epps, played by Michael Fassbender in a vicious and brilliant performance. McQueen shows slavery as the horror it was, and Ejiofor puts a character on the screen that you will never forget.

If you were one of the few people who saw 2011โ€™s Pariah, you know that Adepero Oduye is a stellar actress, as she further proves here as Eliza, a woman sold into slavery and taken from her children. Relative newcomer Lupita Nyongโ€™o is equally heartbreaking as Patsey, a victim of Eppsโ€™s sick abuse.

The movie is shocking, violent and unrelenting in its mission to show this country in its most shameful days. Itโ€™s about time somebody had the guts to make a movie like this.
