Oliver Stone later admitted that everyone involved told him Daryl Hannah was miscast, but he was too proud to replace her. This caused tension on set, particularly with Sean Young who wanted the role herself.
From the beginning, Sean Young kept telling Oliver Stone that she should play Darien and Daryl Hannah should be fired. Young would show up on the set late and unprepared. It's part of the reason her role is so small.
At the time, Michael Douglas was better known as a producer. Oliver Stone was warned that Douglas would micromanage the film and undermine Stone. Stone hired Douglas anyway, and Douglas did not micromanage.
Oliver Stone wanted to make a film about the 1950s quiz show scandals. When he tossed around ideas with his friend Stanley Weiser, he hit on the notion of making a film about Wall Street instead. Weiser was reluctant because he knew very little about the financial markets. Stone encouraged Weiser to read "Crime and Punishment" and "The Great Gatsby" for an idea of the morality he wanted to put into the story, and Weiser spent the next few months immersing himself in the financial world. He and Stone spent three weeks visiting brokerage houses and interviewing investors.
Daryl Hannah has never seen the film. She said in an interview that it was a "rough experience" and she and Director Oliver Stone had an "unhealthy working relationship". At the time of filming she accused Stone of being a misogynist. She said "film is a collaborate medium. Sometimes you hook up with people you don't collaborate well with."

Gordon Gekko's "Greed is good" speech was inspired by Ivan Boesky's speech at the University of California's commencement ceremony in 1986. Boesky was a Wall Street arbitrageur who paid a $100 million penalty to the SEC later that year to settle insider trading charges. In his speech, Boesky said "Greed is all right, by the way. I want you to know that. I think greed is healthy. You can be greedy and still feel good about yourself."
Anacott Steel, a fictional company, may be an obscure reference to Anaconda Copper, a company that busted in the 1929 stock market crash. Many entertainers had invested in Anaconda, including Groucho Marx.

At the Teldar Paper shareholders meeting, the name card of the man at the end of the back row on the right, visible over Gordon Gekko's shoulder, says "Sean Stone". Oliver Stone's son, Sean Stone, plays Rudy Gekko.
The scene where Bud confronts Gekko in his office is primarily composed of two extended takes, separated by the cut to the reverse angle shot of Gordon shouting "Because it's wreckable!" The rest of the scene is one unbroken take.
