Actor and former California Govenor Arnold Schwarzenegger has debuted on the US version of 'The Apprentice'.

'The Terminator' star has taken over from Donald Trump, who will shortly become the president of the United States.

Schwarzenegger is now the boss over 16 celebrities - including 'Culture Club' singer Boy George.

The celebrities are competing to be crowned the winner for their favourite charities.

But in a twist, the show has been moved from New York to to Los Angeles for its eighth season.

Advising Schwarzenegger in his new role is investment guru Warren Buffett, former Microsoft CEO Steve Ballmer, supermodel and actress Tyra Banks and Schwarzenegger's nephew, Patrick Knapp Schwarzenegger.

NBC says Patrick Knapp Schwarzenegger is the actor's "trusted confidante".

This season's winner will gain the title of the Celebrity Apprentice, and a US$250,000 cheque to give to their designated charity.
