The 2015 Academy Award nominations have received some pointed criticism this year for overwhelmingly excluding nominees of color. Chief among the complaints were on behalf of Selma, the movie dramatizing Martin Luther King Jr.’s historic march for equality. Despite heavy Oscar buzz, the film was virtually shut out at the nominations, with no nod to its director, Ava Duvernay, or its lead actor, David Oyelowo, both of whom were expected to be recognized.

Lorraine Toussaint, one of the stars of the film, had a message for Hollywood about inclusion, speaking on the red carpet at the Critics’ Choice Awards.

“Come on already!” said Toussaint. “We are America. This is Hollywood. We really are the leaders of this medium and this medium is powerful. It could change minds and it can change hearts. You must be more responsible with the films that you make and the faces you put out there. All white films no longer reflect the face of this world. Let’s get on with it, shall we?”

Carmen Ejogo, who portrays Coretta Scott King in Selma, actively campaigned for her part, flying to Los Angeles on her “own dime to meet Ava and to fight for the role in a way that I have never fought for a role before.

“There has to be more diversity going forward,” said Ejogo, adding, “I think it keeps the Academy relevant if they keep up to speed in that way.”

Twitter reacted with outrage to the Academy’s lack of nominations for people of color, with one user snarkily commenting, “I guess white men can *finally* have their day in the sun, you know? #OscarNoms,”

On Friday, the White House hosted a private screening of Selma. Stars in attendance included Oprah Winfrey, Oyelowo, Duvernay and Ejogo, Tim Roth and Common.
