For an academy awards that is dripping in anticipation and curiosity. And the Oscar goes to -- And the Oscar goes to -- And the Oscar goes to -- Reporter: With just hours to go stars like Serena Williams, Samuel L.

But before those awards are handed out, the oscars will open with queen. ?????? in the spotlight after the success of "Bohemian rhapsody." ??? We will, we will rock you ??? but the show will be hostless for the first time in 30 years since Rob Lowe and snow white performed this opening number. ??? Keep the cameras rolling ??? It's going to be fun to watch and we get to honor all these folks in the 24 categories. Reporter: Questions about the show's emcee sprouted after Kevin hart stepped down from the gig following backlash over old homophobic tweets that resurfaced. The offer was made. It was received. I was excited. Things happened. They didn't work out the way they should have. Reporter: The category for best picture remains wide open. And potential firsts loom for the films with Netflix landing their first best picture nomination with "Roma." It could be the first foreign language film to take home best picture and its star could be the first ever indigenous Mexican woman to win best actress in a leading role, a newbie to the Hollywood scene. Is this your king, huh? Reporter: "Black panther" already a winner at the sag awards could be the first superhero movie to win a title and it's the seventh nomination for Glenn close who could win her first Oscar for her role in "The wife." If you are trolling for nuggets, you'll find nothing here. Reporter: And one of the most anticipated categories of the night, original song nominees lady gaga and Bradley cooper will perform their hit "Shallow" from "A star is born." ??? Tell me something, boy ??? Reporter: So it's amazing. This really is a year of firsts. Lady gaga as you heard could be the first to ever win a best actress and best original song Oscar in the same year. Spike Lee could be the first African-American to win the Oscar for best director, and Alfonso cuaron could be the first to win for best director and best cinematography. That's for "Roma," you guys.
