LOS ANGELES (Variety.com) - Hollywood leaders are supporting a nationwide protest of the Ferguson grand jury decision Monday not to indict police officer Darren Wilson for the killing of Michael Brown, under the social media hashtag #BlackoutFriday and organized through the collective Blackout for Human Rights.

"Fruitvale Station" director Ryan Coogler, "Selma" helmer Ava DuVernay, "Grey's Anatomy" actor Jesse Williams, Russell Simmons, Michael B. Jordan and others have voiced their support for Blackout Friday, an effort to "make Black Friday (November 28, 2014) a nationwide day of action and retail boycott."

"Blackout will be organizing grassroots events, nationwide, for people to come out and show their solidarity in the fight for equal human rights," read the website.

DuVernay will moderate a Q&A session Friday following a screening series presented by African American Film Festival Releasing Movement at the Downtown Independent in Los Angeles, which will feature "Fruitvale Station," DuVernay's "Middle of Nowhere" and "25 to Life."
