we have to write a essay comparing the characters in Macbeth and the movie " Wall Street " i think we can compare Macbeth with Bud fox.....

Wall Street is analogous more to Dr. Faustus or Faust.  Bud Fox sells his soul to Gordon Gekko the same way Faustus sells his soul to the devil.

Macbeth is both hero and villain.  Mainly villain.  He conspires with Lady Macbeth in the murder of Duncan.  He consults the witches to predict the future.  He is defeated by the loyal thane Macduff.

This is not Bud Fox.  It's Gordon Gekko.  He's Macbeth.

Gordon is both heroic and villainous.  He's a rags-to-riches American success story.  A self-made millionaire.  A Great Gatsby.  But, he also has no soul.  He's so ruthless that he would sell out anyone, which shows you why he has no friends.

But, above all, he's got the best lines in the script.  He manipulates language like the great orator Macbeth.  In his famous  monologue, he says, "Greed--for lack of a better word--is good."  This shows the same equivocation that Macbeth uses to justify his misdeeds.  This is the end justifies the means of Machiavellian politics.

Bud Fox is more like a Witch, Lady Macbeth, Banquo, and Macduff all in one.  He is Witch, an inside trader who tells Gekko of the future (deal with Anacott Steel).  He conspires with Gekko like Lady Macbeth did with her husband, but then he grows a conscience and feels extreme guilt, like Lady M.  Fox differs from Gekko's other inside traders in the same way that Banquo differs from Macbeth regarding the witches' prophecies.  And, in the end, Bud joins up with his father (Old Siward) and the securities police (the English army) to defeat Gekko.
