Citing a violation of campaign regulations, the motion picture academy announced Saturday that it has rescinded the Oscar nomination for sound mixer Greg P. Russell from “13 Hours: The Secret Soldiers of Benghazi.”

“The decision was prompted by the discovery that Russell had called his fellow members of the sound branch during the nominations phase to make them aware of his work on the film, in direct violation of a campaign regulation that prohibits telephone lobbying,” the academy said in a statement.

The remaining sound mixers from “Benghazi” — Gary Summers, Jeffrey J. Haboush and Mac Ruth — will remain as nominees.

What inspired the film’s chopped and screwed score?

We were talking, and initially I was feeling the poetry of the film. I was trying to channel that idea of poetry into music and then Barry [Jenkins, the director of "Moonlight"] told me about how much he loved chopped and screwed music.

We just had this idea where like, what if I wrote and fully recorded my music, my classical orchestral music, and then what if we chopped and screwed it as like a second part of the process? That’s one of those things where I think it sounds cool, but you don’t know if it’s going to work, you know? And what’s cool with film music is you don’t know until you put it up against the picture if it’s right. You really don’t know. And what was amazing was as we started doing these explorations, it totally worked. It felt like it was part of the movie. It felt like it was a way of evolving the music along with Chiron’s own personal journey, and that was really exciting. And certain places we would do different experiments.

What’s cool with film music is you don’t know until you put it up against the picture if it’s right. You really don’t know.

Some of the tracks are bent so far down that they’re just like a rumbling, like during the schoolyard fight, some of them are actually more like cellos that I would bend and they sound kind of like basses. It’s always different… most of the cues have some element which is evolved in some way.

Last month, you did a live orchestration to accompany the film. What was it like to do a live orchestration while the film is going on?
That was unforgettable for me. It actually took a long time to prepare for that. I worked on it for almost three months, because with the chopping and screwing, some of that is actually not playable on the instruments. You take a violin and you bend it and then you get it to a range where the violin can’t play it. So I spent a lot of time figuring out how do we do it live because when you’re playing with it live you want it to be live. So there were places, for example, where I would have a violin that I bent to sound like a bass so we’d have a bass play it. So I would sort of reassign some things.

Why do the Oscars still matter?
I think it’s very special for there to be a celebration that is really a celebration of the arts. It’s a celebration of people’s artistic work, and especially in the world today, I think it’s something that’s really important that people have an opportunity to showcase what they’ve done and also for the audience to respond to those works. So I view it as, all the people here are artists in their own way. Every department of the film, these are real masters of their craft. So I think it’s wonderful that there are these celebrations.

Trayvon Martin. (Facebook)

Before Sunday’s Oscars celebration, director Ava DuVernay and other stars are donning hoodies to honor Trayvon Martin on the fifth anniversary of his death.

DuVernay, who’s nominated for documentary feature for her film "13th," tweeted a photo of herself holding up a gray hoodie, similar to the one Martin was wearing when George Zimmerman shot and killed him, emblazoned with "TRAYVON" in black letters.

This may be the best that Taraji P. Henson has ever looked on a red carpet. Elegant and sexy in custom Alberta Ferretti, she looks like a cross between a Hollywood siren and a John Singer Sargent portrait.

Jackie Chan managed a plus-two for the red carpet — he showed up with two toy pandas, one boy and one girl, wearing UNICEF pins.

The martial-arts icon is a goodwill ambassador for the charity, and he’s been taking stuffed pandas Chan La and Chan Zy on the road for years now.

Emma Roberts’ red-carpet ensemble shows that "sustainable fashion" doesn’t necessarily mean "made out of recycled soda bottles."

Roberts, one of the stars on this year’s red carpet raising awareness of sustainable style through Suzy Amis Cameron’s Red Carpet Green Dress program (another is Priyanka Rose), turned out wearing an Armani Privé gown from the designer’s first Privé collection, which debuted in Paris in January 2005.

It’s a spaghetti strap couture dress embroidered with cream crystals and waves of small white jet beads featured in a two-tiered skirt. The plunging bodice is made of jet and black crystal teardrops, and the look is finished off with a black satin cummerbund.

There’s power in telling untold stories.

"It’s given people a lot of hope. It’s given a lot of inspiration to little girls and little boys," said "Hidden Figures" screenwriter Allison Schroeder. "My favorite thing is when kids are outraged by the racism, outraged by the segregation."

The film, which tells the story of three black female mathematicians working for NASA, is nominated for adapted screenplay, best picture and supporting actress.

For Schroeder, success did not come overnight.

"I struggled for years and years and years," she said. "So I just celebrate people putting their heart and soul into something despite the odds against them."

She shares her nomination with fellow screenwriter Theodore Melfi.

A small crowd gathered in Hollywood Sunday afternoon to protest celebrities.

A small group of President Trump supporters rallied Sunday in Hollywood in advance of the Academy Awards.

The group held its demonstration outside the Metro station near the corner of Hollywood and Vine, not far from the Dolby Theatre, where the Oscars ceremony will be held.

About a dozen protesters carried signs, Trump banners and American flags, chanting such slogans as “Celebrities don’t speak for us” and “Hollywood, don’t divide us.”

The protest was called by the San Fernando Valley for Trump Celebration group, which said it believed “Hollywood elites” were trying to divide America.

Academy Award attendees on Sunday made activism a must-have red-carpet accessory.

Those blue ribbons affixed to the formal attire worn by model Karlie Kloss, original song nominee Lin-Manuel Miranda, "Loving" nominee Ruth Negga and "Moonlight" director Barry Jenkins represent the American Civil Liberties Union’s new "Stand With ACLU" initiative.

By wearing the pin, the celebrities are showing their support “for the rights and civil liberties guaranteed by the Constitution to everyone in the United States," the ACLU said in a statement.

"I’m wearing an ACLU ribbon because they’re fighting incredible fights right now for American ideals," Miranda said .
