Michael Douglas' role as ruthless trader GORDON GEKKO didn't teach him to stay away from the stock market - he lost 40 per cent of his vast wealth in the 2008 banking crisis.
Douglas won an Oscar playing villainous bonds boss Gekko in 1987's Wall Street, in which the character famously said, "Greed is good."
But any tips he picked up from trading on the markets through his movie role were lost when the global economic crisis hit the U.S. in late 2008, leaving many bankable stocks worthless.
And Douglas - who is estimated to be worth $140 million (£93 million) - admits he pulled out of the stocks business completely after losing almost half of his entire fortune.
He tells Britain's Esquire magazine, "I lost 35-40 per cent of my net worth on the 2008 crash. I played. Years ago, through the tech booms, I definitely did it.
"At the end of last year, I took a whole bunch out."
