Wall Street (1987)

In writer/director Oliver Stone's cautionary treatise on the Me-Decade of stock trading:

• the notorious "Greed is...good" monologue ("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"), delivered by predatory, slithery and ruthless, money-mad corporate financial trader Gordon Gekko (Oscar-winning Michael Douglas) to the annual shareholders' meeting of Teldar Paper
• the scene of young stockbroker Bud Fox (Charlie Sheen) questioning him about his exorbitant wealth: ("So tell me, Gordon--when does it all end, huh? How many yachts can you water-ski behind? How much is enough?") and Gekko's reply about how he made the rules in the free market: ("It's not a question of enough, pal. It's a zero sum game. Somebody wins, somebody loses. Money itself isn't lost or made, it's simply, uh, transferred from one perception to another. Like magic. This painting here - I bought it 10 years ago for $60,000. I could sell it today for $600. The illusion has become real. And the more real it becomes, the more desperate they want it. Capitalism at its finest")
• the climactic scene when Gekko angrily raged at Bud and slapped him around - revealed later to be recorded by investigators: ("I took you in! A nobody! I opened the doors for you!...I showed you how the system works!...") when Bud was assured: "You did the right thing"
