Michael Douglas, who played a greedy executive in the movie Wall Street, is the Federal Bureau of Investigation's new spokesman against insider trading.

迈克尔·道格拉斯——电影《华尔街》中扮演一个贪婪的经理，新任联邦调查局反内线交易发言人。

Some high-profile hedge fund managers have been found guilty of insider trading in recent years
In the movie, Mr Douglas played the character Gordon Gekko who famously boasted that "greed is good."

For critics the phrase came to embody¹ the excesses of the Wall Street boom years and subsequent problems.

However, in his new role Mr Douglas is warning executives against following his on-screen credo（信条，教义） .

"The movie was fiction（小说，虚构） , but the problem is real," he said in an announcement.

"Our economy is increasingly dependent on the success and integrity of the financial markets. If a deal looks too good to be true, it probably is."

'Integrity and fairness'

The move is a part of Federal Bureau of Investigation's (FBI) efforts to tackle insider trading and fraud.

Last year, Raj Rajaratnam, a former hedge-fund manager and founder² of Galleon³ Group, was sentenced to 11 years in jail and fined $10m (£6.4m) for one of the biggest insider trading cases in American history.

The case saw more than two dozen other people being jailed, with sentences ranging from a few months to 10 years.

The FBI said that it will continue to "pursue those who cheat the system."

"Integrity and fairness are paramount⁴ to（优于，高于） the success of our markets. Today's announcement brings us closer to that objective," said the FBI's Assistant Director in Charge, Janice Fedarcyk.
