Gordon Gekko changes sides, works for FBI

The man who popularized the phrase "greed is good" is changing teams.

Michael Douglas, who played the greedy insider-trading antihero Gordon Gekko in the 1987 film "Wall Street" and the 2010 movie "Wall Street: Money Never Sleeps," has taped a public service announcement for the FBI warning about the dangers of Wall Street shenanigans.

In the PSA, Douglas says: "The movie is fiction, but the problem is real." He also urges those who suspect foul play to submit it to www.fbi.gov .

In the first "Wall Street" movie, Gekko is found guilty of several securities violations and is sent to prison for his crimes.

And just for fun, here is what Gekko had to say about greed:

Greed, for lack of a better word, is good. Greed is right. Greed works. Greed clarifies, cuts through, and captures, the essence of the evolutionary spirit. Greed, in all of its forms; greed for life, for money, for love, knowledge, has marked the upward surge of mankind.
