Margot told Murphy, "One of your producers, Chuck Roven, called me, because we worked together on some other projects. And 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.’ And he’s like, ‘We’re not moving our date. I just think it’d be better for you to move.’ And I was like, ‘We’re not moving!’ I think this is a really great pairing, actually. It’s a perfect double billing, 'Oppenheimer' and 'Barbie.'" Upon hearing this, the 'Peaky Blinders' star responded, "That was a good instinct."
