African-American director Spike Lee and actress Jada Pinkett Smith say they will boycott next month’s Academy Awards ceremony because black actors were shut out of the Oscar nominations.

The Oscar acting nominees announced on Thursday lacked black performers for the second year in a row.

The lack of African American nominees led to the revival of the Twitter feed #OscarsSoWhite which had emerged in 2015.

Lee, the director of such films as Do the Right Thing and 2015’s Chi-Raq, said on Monday that he was coinciding his boycott announcement with the national holiday commemorating slain civil rights leader Martin Luther King Jr.

“How Is It Possible For The 2nd Consecutive Year All 20 Contenders Under The Actor Category Are White? And Let’s Not Even Get Into The Other Branches,” Lee wrote under the #OscarsSoWhite hashtag.
