For the second year in a row, the Academy did not nominate any black actor to any of the 20 slots in the four acting categories.
If last year's minority-free acting nominations led to the protest hashtag #OscarsSoWhite, this year's all-white lineup is sure to trigger a fresh expression of outrage.
"Straight Outta Compton", the drama about the rise of the rap group NWA, although got an original screenwriting nomination, failed to earn a best picture nomination, even though the critically acclaimed movie has been recognised by other groups like SAG-AFTRA, which nominated its cast for a best ensemble award.
Academy president Cheryl Boone Isaacs has also announced a new initiative called A2020 to further diversify the Academy itself and also encourage the industry to open up more opportunities for women and minorities.

This year, only a handful of awards-caliber films focused on black stories, like Compton or the Africa-set Beasts of "No Nation", or featured black actors in prominent roles like Smith in "Concussion", Jordan and director Ryan Coogler of "Creed", Elba in "Beasts" and Samuel L Jackson in "The Hateful Eight".
Elba was nominated by BAFTA, SAG-AFTRA and the Golden Globes for his performance as an African warlord in Beasts, and Del Toro, a past Oscar winner for Traffic, was nominated by BAFTA for Sicario. But they failed to gain nomination at Oscars.
