Released thirty years ago, Wall Street of Oliver Stone immerses deep inside the American finance at the time of the big deregulation pushed by the President Reagan. Eighties were the golden age, time of unconditionnal speculation and greed for the golden boys, embodied in the movie by the character of Gordon Gekko. Played by Michael Douglas, Gekko was inspired by all the kings of Stock Exchange at that time. Rémi Lainé tries to find the intimate reasons that pushed Oliver Stone to make Wall Street and his quasi-ethnological ambition. We find out that Donald Trump takes over the Gekko’s mythical statement in the movie : «Greed is good ». From that point of view, Wall Street is really topical.
