(CNN) -- The nominees for the 91st Academy Awards were revealed Tuesday morning.

"Roma," a Netflix film that looks back at director Alfonso Cuarón's youth in Mexico, and "The Favourite," a period dramedy with an all-star cast, tied for most nominations with ten each.

"Black Panther" made history as the first superhero film to ever be nominated for best picture.

The Marvel mega-hit was joined in that category by "BlacKkKlansman," "Bohemian Rhapsody," "The Favourite," "Green Book," "Roma," "A Star Is Born" and "Vice."

Without a clear frontrunner for best picture among popular favorites, or as of yet a host, this year's Oscar ceremony is shaping up to be particularly unpredictable.

Observers had been interested in a potential best actress race between Glenn Close for her role in "The Wife" and Lady Gaga for her performance in "A Star Is Born," and they got their wish with Tuesday's announcement.

Close took the trophy in that category at the Golden Globes, and the pair tied for best actress at the Critics' Choice Awards.

Yalitza Aparicio ("Roma"), Olivia Colman ("The Favourite") and Melissa McCarthy ("Can You Ever Forgive Me?") were also nominated for best actress.

CNN Film's "RBG" scored a nod for best documentary feature. The film's theme song, "I'll Fight," by Jennifer Hudson and Diane Warren, was nominated for best song.

The Oscars will air live February 24 on ABC.
