Films featuring black actors were shut out of the main categories when the nominations for the 2016 Academy Awards were announced this morning, prompting some movie fans to voice their outrage on social media.

No people of color were nominated for best actor, best actress, best supporting actor, or best supporting actress and no films featuring African-American actors were nominated in the best picture category.

“Straight Outta Compton,” a well-reviewed film featuring African-American actors, quickly began trending on Twitter. Other outraged awards-watchers began tweeting with the hashtag #OscarsSoWhite.

Some of the movies that some critics had expected to be contenders, like “Straight Outta Compton” and “Creed,” had to settle for lesser nominations. Idris Elba had drawn some rave reviews for his performance in "Beasts of No Nation," and Will Smith had drawn attention for his role in "Concussion," but neither earned a nod. Benicio Del Toro was also passed over for his acclaimed performance in "Sicario."

Sylvester Stallone earned a nomination for best supporting actor for “Creed.”
