The film '12 Years a Slave' was awarded Best Picture at the 86th Academy Awards in March 2014 [1]. The movie is a historical drama directed by Steve McQueen and produced by Brad Pitt. It is based on the 1853 memoir of the same name written by Solomon Northup, a free Black man from New York who was kidnapped and sold into slavery in the American South [3]. While Steve McQueen directed the film and Brad Pitt served as a producer and actor, the original literary work and the life story it depicts belong to Northup [3]. Matthew McConaughey, though mentioned in the options, won the Best Actor award at the same ceremony for 'Dallas Buyers Club' [2]. The memoir remains a significant historical document detailing the horrors of the antebellum slave system [3].
