Margot Robbie worried Leonardo DiCaprio slap would get her arrested during 'Wolf of Wall Street' audition

The impromptu moment came while the two were supposed to be reading a kissing scene. However, Robbie decided another move would work better for the script. The last line from DiCaprio was, "Come over here and kiss me."

"And it was dead silence for what felt like an eternity but was probably three seconds," recounted the actress, who was 22 years old at the time. "And then they just burst out laughing. Leo and Marty were laughing so hard, they said, 'That was great.'"

Afterward, Robbie worried she would get "arrested" and ruin her career over the off-script move.

"I was like, 'You're going to get arrested, I'm pretty sure that's assault, battery,'" she thought at the time. "Not only will you never work again, but actually you will go to jail for this, you idiot. And also, why did you have to do it so hard? You could have done it lighter."

Robbie's role as Naomi Lapaglia in "Wolf of Wall Street," alongside DiCaprio, Jonah Hill and Matthew McConaughey, thrust the young star straight into the spotlight. The film was based on the real-life story of Jordan Belfort, a former stockbroker who committed financial crimes, including stock market manipulation and fraud.

The "Barbie" actress wasn't prepared for the newfound level of fame the role brought her.

"And she just looked at me, completely straight-faced, and was like, 'Darling, I think it's too late not to.' That's when I realized the only way was forward."

These days, Robbie is much more comfortable navigating her stardom.

"I know how to go through airports, and now I know who's trying to f--- me over in what ways," Robbie explained to the outlet.

After "The Wolf of Wall Street," the actress landed roles in huge films including "I, Tonya," "Suicide Squad" and "Once Upon a Time in Hollywood."
