It Looks Like We Actually Got Barbenheimer This Summer Because Margot Robbie Stood Up To An “Oppenheimer” Producer Who Asked Her To Change The “Barbie” Release Date

“I cannot believe the Barbenheimer phenomenon was born out of Margot Robbie (lead actress/producer) standing up to a man,” one fan said.

Of all the standout moments of 2023, Barbenheimer — aka the joint release of Greta Gerwig’s Barbie and Christopher Nolan’s Oppenheimer — was definitely one of the most iconic.

Both of the highly anticipated films proved to be huge successes. Barbie reportedly grossed $162 million domestically in the box office during its first weekend in theaters, beating out Oppenheimer, which is said to have brought in $82.4 million.

Now, months later, the leading actors of Barbie and OppenheimerMargot Robbie and Cillian Murphy respectively — have sat down one-on-one for Variety's Actors on Actors series to discuss their projects.

Speaking about the iconic release of both films on the same day, which was July 21, Margot revealed to Cillian that an Oppenheimer producer — Chuck Roven — allegedly initially asked her to move Barbie’s release date.

“One of your producers, Chuck Roven, called me, because we worked together on some other projects,” claimed Margot, who coproduced Barbie alongside Greta.

“He was like, ‘I think you guys should move your date.’ And I was like, ‘We’re not moving our date. If you’re scared to be up against us, then you move your date,’” Margot recalled.

“He was like, ‘We’re not moving our date, I just think it'd be better for you to move,’” Margot claimed Chuck said.

Cillian told Margot, “That was a good instinct,” while the pair went on to discuss how the success of each film demonstrates the wide-ranging “appetite that the audience has for cinema.”

Cillian added that the public ultimately generated the “interest” around Barbenheimer themselves, which obviously largely contributed to both film’s successes.
