The film was made 1980's or 1990's; set in modern times. "King of Denmark" is now CEO of a pharmaceutical company. This is NOT the Hamlet starring Ethan Hawke & Julia Stiles.

I am taking a shot in the dark here so I am sorry if this isn't the movie you are thinking about. The only modern Hamlet that I can think of which isn't a foreign film, is set in a wealthy corporate backdrop, AND isn't the Ethan Hawke movie, is Let The Devil Wear Black. Release date was 1998.
