Two weeks ago, the British agency that worked on the “Wheel of Time” spot, Amplify, brought it to Times Square. (Amazon founder Jeff Bezos owns The Washington Post.) In that ad, actress Rosamund Pike, whose character Moiraine represents what the series imagines as “the light,” reaches out her hand, beckoning for help. The Fade, an agent of “the darkness,” reaches out his mouth, looking for a city bus to devour. The effect, which can give passersby the impulse to duck, is a leap ahead of the area’s famous steaming cup of soup.
