"She clinched her part in The Wolf of Wall Street during our first meeting," wrote Scorsese, "by hauling off and giving Leonardo DiCaprio a thunderclap of a slap on the face, an improvisation that stunned us all."
Robbie spoke with Harper's Bazaar about the audition two years ago, saying she saw the opportunity as a "once in a lifetime chance" she had to take.
"I start screaming at him and he's yelling back at me. And he's really scary. I can barely keep up. And he ends it saying, 'You should be happy to have a husband like me. Now get over here and kiss me.' So I walk up really close to his face and then I'm like, maybe I should kiss him? When else am I ever going to get a chance to kiss Leo DiCaprio, ever? But another part of my brain clicks and I just go, whack! I hit him in the face. And then I scream, 'Fuck you!' And that's not in the script at all. The room just went dead silent and I froze."
At first, Robbie was worried DiCaprio might have her arrested for assault, but luckily, Scorsese and DiCaprio just burst out laughing – and DiCaprio even asked Robbie to hit him again.
