‘Oppenheimer’ star Emma Dumont comes out as trans masculine non-binary, changes name

“Oppenheimer” star Emma Dumont has come out as trans masculine non-binary and has chosen a new name to be called for close friends and family.

The 30-year-old actor, who played Cillian Murphy’s sister-in-law Jackie in the Oscar-winning film, now uses “they/them” pronouns and reflected the change on their Instagram story along with a new name – Nick Dumont.

The change in names will only be used by family and friends as Dumont will remain with the stage name Emma as will their Instagram handle.

“They identify as a trans masculine non-binary person. Their work name is still going to be Emma Dumont, but they will go by Nick with friends and family,” a rep told TMZ.

The term transmasculine is used to refer to several different groups of people, all of whom were assigned female at birth (AFAB) but identify with masculinity, including transgender males, and AFAB nonbinary.

Dumont last posted on Instagram on Dec. 3, a four-photo slideshow of themselves, but has not publically addressed their coming out.

Dumont, born Emma Noel Roberts, has over 25 acting credits since 2009, but found large success from Christopher Nolan’s 2023 biopic of J. Robert Oppenheimer.

In the heavily acclaimed film, the 30-year-old played Oppenheimer’s sister-in-law Jackie.

Before the World World II drama, Dumont was Lorna Dane’s Polaris in Marvel’s “The Gifted,” Hulu’s “T@gged” and appeared in a 2017 episode of “Pretty Little Liars.”

They are expected to star in the unscheduled thriller “New Me,” with the poster crediting Emma Dumont as the lead actor.
