George Clooney's possible run for the governship of California could become the latest instalment in a long-running story of US celebrities moving into the political arena.

Arnold Schwarzenegger is an obvious example of another huge Hollywood star who successfully made the transition from silver screen to State House.

The Austrian body-builder triumphed over Democrat Gray Davis in the 2003 race.

There were even whispers that he might run for the Presidency at some point, although sceptics pointed out that American law forbids those born outside the country from reaching the highest office.

One man who did make the transition from California governor to president was Ronald Reagan.

Perhaps less well known now is that Reagan was also a film star, appearing in dozens of features spanning four decades from 1937 to 1964.

Although the field of stars who have embraced politics is somewhat male-dominated, 1930s child star Shirley Temple, who passed away in February, went on to have a distinguished career as a diplomat.

She reportedly got her chance after senior Republican Henry Kissinger heard her discussing foreign affairs at a party and was taken aback by the depth of her knowledge.

Another entertainer who stepped into politics was former Minnesota governor Jesse 'The Body' Ventura, who was a huge star of WWF wrestling.

Ventura is also an author, TV presenter and actor - indeed he appeared in blockbuster hit Predator alongside fellow thespian-turned-politician Schwarzenegger.

He is tipped for a run at the White House in 2016, even if his chances of success look at best remote, given that he would almost certainly run as an independent candidate, without the backing of either major party.
