Twitter roasts lack of nominee diversity with #OscarsSoWhite

Last year's Academy Awards winners featured more diversity, thanks to "12 Years a Slave." The movie won best picture, Lupita Nyong'o won a best supporting actress Oscar and Chiwetel Ejiofor was nominated for best actor.

"12 Years" also was nominated for best costume design, best film editing and best production design, while "Mandela: Long Walk to Freedom" produced a best-song nomination.

This year it's Atlanta-filmed "Selma" offering diversity. The moviea, bout the Selma-to-Montgomery march movement, is up for best song and best picture. It was directed by Ava DuVernay, the first black woman to win best-director honors at Sundance, for "Middle of Nowhere."

DuVernay was nominated for a best director Golden Globe, but not for a corresponding Academy Award. She noted the timing of today's announcement, calling the Oscar love "Selma" did receive a birthday gift to Rev. Martin Luther King Jr., whose birthday would have been today.

While the Twittersphere has congratulated "Selma" for its prestigious best picture nomination many were disappointed that DuVernay is not up for best director and the David Oyelowo, who was Golden Globe nominated for his starring role as King, did not receive a best-actor Oscars nod.
