Margot Robbie has made an admission about being punched by Leonardo DiCaprio in Wolf of Wall Street

The Wolf of Wall Street is that chock-a-block with drama, drugs and deceit that it's hard to remember every minute detail.

But as we all know, the legendary Martin Scorsese doesn't just include stuff for the sake of it - each scene is carefully crafted and adds another piece to the puzzle of the plot.

However, he also let the stars of the 2013 film exercise some creative control over their performances, encouraging them to improvise and act on impulse - just like the real Jordan Belfort and his ex-wife Nadine Macaluso would have.

Leonardo DiCaprio and Margot Robbie portrayed the volatile couple in The Wolf of Wall Street, and it's fair to say the pair of them absolutely aced it - which they both reckon is down to their willingness to go the extra mile.

We already know that Margot insisted on being starkers for that iconic scene where she turns up naked in the doorway, but I'll bet you didn't know that she helped orchestrate a ferocious scrap between her and her co-star.

While discussing some of the behind-the-scenes secrets which helped to make The Wolf of Wall Street such a good watch, the Barbie actor explained that her final scene in the film was actually put together at the eleventh hour.

As Jordan's (DiCaprio) legal troubles mount, so does his reliance on drugs - and Naomi's had it up to here with him.

He's sliced the sofa in search of cocaine and she bursts in the room to give him a piece of her mind, as well as the news that she is divorcing him - and that he'll never see their child again.

In one of the most emotional scenes in The Wolf of Wall Street, Jordan shoves past her and heads towards his daughter's room, intent on fleeing with the youngster, but things turn violent when Naomi tries to stop him.

The stockbroker punches his wife in the stomach in his rage before grabbing their daughter and racing to his car, but as film fans will remember, he doesn't get very far in his drug-addled state and crashes the car in the driveway.

Viewers would likely presume that Scorsese spent weeks stewing over this break-up scene - but according to Margot, they actually only came up with the idea the night before shooting it.

The 33-year-old explained: "Everyone is just so committed to making the best movie possible, that everyone just goes further and further with it.

"Marty [Scorsese] just lets you improvise for five minutes, do whatever you feel like doing. The last scene that Naomi is in, we completely made it up the night before shooting it.

"And it went from being conversation to kidnapping and drugs and punching each other and smashing windows.

"It just went in a whole different direction."

Then again, we shouldn't expect anything less from Margot - seen as though she booked The Wolf of Wall Street by slapping Leonardo in the face off the cuff during her audition.

Speaking to Harper’s Bazaar, she previously explained that she came up with the move on the spot as she realised she needed to do something special to impress Scorsese.

The Aussie star said that she was aware her audition was nearly over and that it was a 'once-in-a-lifetime chance', so she pulled out the big guns.

She explained: "So I start screaming at him [Leonardo] 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, 'F*** you!'

"And that's not in the script at all. The room just went dead silent and I froze."

Moral of the story - Margot's hard as f*ck.
