Idris Elba received a Golden Globe Best Actor nomination for his roles as Mandela in the movie;Mandela: Long Walk To Freedom', while Chiwetel Ejiofor got his Best Actor nomination for his role as Solomon Northup in the movie, 12 Years A Slave. Chiwetel also got a SAG Awards nomination.
I haven't seen any of the movies, if you have, who do you think deserves win? The two actors are up against, Tom Hanks - Captain Phillips, Matthew McConaughey - Dallas Buyers Club and Robert Redford for All is Lost.
