In the video, Douglas, who played Gekko in the 1987 Oliver Stone film, "Wall Street" and its sequel, "Wall Street: Money Never Sleeps," tells viewers that "the movie was fiction, but the problem is real. Our economy is increasingly dependent on the success and the integrity of the financial markets. If a deal looks too good to be true, it probably is."
The one-minute PSA also features a clip of Douglas uttering one of Gekko's most quotable lines from "Wall Street": "Greed, for lack of a better word, is good. Greed is right."

Douglas' latest film was the Steven Soderbergh action-thriller "Haywire."
