“Oppenheimer,” starring Cillian Murphy, landed four SAG nominations, tying for the most nominations with its ‘Barbenheimer’ partner “Barbie.”

Murphy was nominated in the Outstanding Performance by a Male Actor in a Leading Role category for his portrayal of J. Robert Oppenheimer in Christopher Nolan's summer blockbuster "Oppenheimer."

Murphy's co-stars Robert Downey Jr and Emily Blunt were also both nominated in the Outstanding Performance by a Male Actor in a Supporting Role and Outstanding Performance by a Female Actor in a Supporting Role categories, respectively.

Murphy, Downey Jr, and Blunt were further nominated alongside their "Oppenheimer" castmates Casey Affleck, Kenneth Branagh, Matt Damon, Josh Hartnett, Rami Malek, and Florence Pugh in the Outstanding Performance by a Cast in a Motion Picture category.

The 30th Annual Screen Actors Guild Awards® will honor outstanding individual, cast, and ensemble performances for the past year. SAG notes that of the top industry honors presented to actors, only the SAG Awards are selected entirely by performers’ peers in SAG-AFTRA with 119,515 eligible voters.

Final voting opens on Wednesday, January 17, and closes at noon PT on Friday, February 23. The award ceremony will be streamed live on Netflix on February 24.

The four SAG nominations for "Oppenheimer" come just three days after the film scooped five Golden Globe awards, including Murphy's win in the Best Actor in a Motion Picture - Drama category, on Sunday, January 8.

Notably, Cork native Murphy was nominated alongside two fellow Irish actors in the category - Andrew Scott ("All of Us Strangers") and Barry Keoghan ("Saltburn"), meaning Irish talent made up 50% of the nominees in the category.

"To all my fellow nominees, if you’re Irish or not, you’re all legends," Murphy said in his acceptance speech on Sunday night.
