Margot Robbie’s role as Barbie‘s producer as well as lead actor will see her rake in tens of millions of dollars from the box-office hit.

Since its release, Barbie has defied expectations, beating out Christopher Nolan’s Oppenheimer at the box office and making over $1 billion in ticket sales.

Australian actress Robbie played the leading role in Greta Gerwig’s smash hit, while also serving as the film’s producer through her own company LuckyChap Entertainment.

Three individuals with insider knowledge told Variety that Robbie is set to make $50 million ($77 million) in salary and box office bonuses.

This reported sum is in addition to reported $19 million Robbie made up front.

Margot Robbie’s ‘Barbie’ is a winner at the box office.

Back on the Barbie press tour, Robbie said she was able to pay off her mother’s mortgage after getting paid for The Wolf on Wall Street.

Starring alongside Leonardo DiCaprio in the Martin Scorsese film, it was Robbie’s breakout role that cemented her career in Hollywood.

According to The Independent, Robbie said that her mother would always lend her money in the early years of her career and would often take money out of the mortgage.

Robbie always knew she would eventually pay her mother back.

“And then one day, when I made enough money, I just paid that whole mortgage off completely. I was like, ‘Mum, don’t even worry about that mortgage anymore. It doesn’t even exist anymore’,” Robbie told CBS’s Sunday Morning.

She said she had written down everything she owed her mother.

Barbenheimer continues to dominate

At this point, Barbie is poised to become the top film of 2023.

Gerwig ‘s film phenomenon remained a runaway No. 1 at the US box office in its fourth week, bringing in $US33.7 million ($A51.9 million), according to studio estimates on Sunday.

It has surpassed $US500 million ($A770 million) in North America overall a week after it crossed the $US1 billion ($A1.5 billion) mark globally – a record for a female director.

Greta Gerwig’s Barbie has left studio execs “speechless”.

The second half of the Barbenheimer duo, Oppenheimer, returned to the No. 2 spot in its own fourth week after a week at No. 3 overall.

Even Warner Bros, the studio behind Barbie was shocked at its success.

Jeff Goldstein and Andrew Cripps, who oversee domestic and international distribution for Warner Bros, the studio that produced Barbie.

In a joint statement, they said even they were “speechless”.

“As distribution chiefs, we’re not often rendered speechless by a film’s performance, but Barbillion has blown even our most optimistic predictions out of the water,” they said.
