Americans who want to catch a glimpse of the new US Treasury Secretary need look no further than their local cinema or television set.

Steven Mnuchin [pronounced mi-new-shin], who was confirmed by the Senate on Monday by a mostly party-line vote of 53-47, made his debut on the silver screen in November in Rules Don’t Apply.

The synopsis of the film, which sees an aspiring actress and an ambitious businessman's lives changed in "unpredictable and incredible ways" has some parallels with Donald Trump's own journey to the White House.

Mr Mnuchin the "actor" has a cameo role as a Merrill Lynch banker, but the 53-year-old is no stranger to Wall Street.

Following in the footsteps of his father Robert, he become a banker at Goldman Sachs in 1985 after studying at Yale.

He worked there for 17 years, including working with mortgage backed securities in the mid-1990s, where he rose to the role of vice chairman of the division.

Mr Mnuchin also worked with the man who broke the Bank of England.

Billionaire George Soros hired him in 2003 to start a new business focused on buying risky debt.

SFM Capital Management, Mr Soros's business, was seen by many as Mr Mnuchin's move from banking to the hedge fund industry.
