- When Winthorpe and Valentine arrive at the World Trade Center, Winthorpe tells Valentine “In this building, it’s either kill or be killed”. This line was removed from some TV broadcasts after 2001, out of respect for the victims of the September 11th attacks.
- Randolph and Mortimer Duke later appear in Eddie Murphy’s movie Coming to America, where, in a cameo appearance, the two are homeless on the street and Prince Akeem gives them a large amount of money to get them back off the streets.
- In 2010, as part of the Wall Street Transparency and Accountability Act, which was to regulate financial markets, a rule was included which barred anyone from using secret inside information to corner markets, similar to what the Duke brothers tried to do in the movie. Since the movie inspired this rule, it has since become known as the Eddie Murphy Rule.
