"If I were to take a picture of this crowd right now, people would see some of your faces and the movements that are starting today. This is your moment to join those silent heroes of the past, individuals who stood in the very spot where you stand today. You now have the responsibility to carry the torch as we gather here... as hundreds of thousands did on this day 50 years ago." Movie star Forest Whitaker delivers a stirring address as he marks the 50th anniversary of Martin Luther King's iconic 'I have a dream...' civil rights speech, alongside stars including Jamie Foxx, Oprah Winfrey and Hill Harper and civil rights leaders like Rev. AL Sharpton and Jesse Jackson.
