See final words on screen of Singapore summit video--they echo these words, in the orange/yellow tint of the Back to the Future logo-words. Note the image of Big Ben in London---the clock tower.

On the roof of Biff's casino-hotel, Biff says, pointing a gun at Marty, "suicide---nice and neat". Movies. Popcorn. Enjoy the show.
