There is no denying that the cast of the hit American sitcom Friends was almost all white. Making a few exceptions like Julie and Charlie, almost all the leading and supporting characters were Americans. About 16 years after the show ended, David Schwimmer is opening up about the lack of diversity on Friends and revealed he had been campaigning for years to have his character, Ross, date a woman of colour. The actor made the confession in a recent interview with The Guardian.
