DANIEL KALUUYA, "Judas and the Black Messiah"

Then: The British actor made his Oscars red carpet debut at the 90th Academy Awards where he was nominated for best actor for his breakout role in 2017's "Get Out."

LAKEITH STANFIELD, "Judas and the Black Messiah"

Then: Stanfield made his Oscars debut at the 90th Academy Awards when the actor revived his character in "Get Out" during host Jimmy Kimmel's opening monologue.

This year, the actor is returning to the Oscars, but this time as a nominee for best supporting actor, alongside his "Judas and the Black Messiah" co-star Daniel Kaluuya, who he also appeared with in "Get Out."

Then: A seasoned veteran, Close received her first Academy Award nomination for best supporting actress for 1982's "The World According to Garp."

Could her role in "Hillbilly Elegy" be the one to clinch her the coveted win? Now:

OLIVIA COLMAN, "The Father"

LESLIE ODOM, JR., best supporting actor nominee, "One Night in Miami..."

Odom, Jr. may already have a Tony Award and Grammy Award for his role as Aaron Burr in the musical "Hamilton," but this year, he's hoping to add an Oscar to his list of accolades. The actor and singer received his first Academy Award nod and rave reviews for his role as Sam Cooke in Regina King's directorial debut, "One Night in Miami."

PAUL RACI, best supporting actor nominee, "Sound of Metal"Raci is another newcomer to the awards show circuit, but his career spans decades on film and television.

Director Darius Marder told "IndieWire" that he chose Raci over A-list actors for the role because he was the son of deaf parents and grew up using American Sign Language.

MARIA BAKALOVA, best supporting actress nominee, "Borat Subsequent Moviefilm"

A newcomer to not just the awards show circuit but also to American films, Bakalova wasn't even alive when fellow nominee Glenn Close got her first Oscar nod. The 24-year-old Bulgarian actress and first-time nominee has made waves this year as Tutar Sagdiyev in Sacha Baron Cohen's highly-anticipated "Borat" sequel.

YUH-JUNG YOUN, best supporting actress nominee, "Minari"
