“It’s a globe-trotting exhilarating adventure of a story that is based on the power of the imagination of a young Black boy who finds himself in the worst of circumstances but doesn’t allow those circumstances to dictate his possibilities,” executive producer and star Sterling K. Brown said of the series during a day-long Washington Black-themed activation last month. At the Grove Hotel in London, the cast (including Brown, Kingsley Jr., Karanja, plus scene stealers Iola Evans and Edward Bluemel) gathered for an immersive event that conveyed the spirit of Washington Black. There were hot air balloon installations (if you know the story, you know the significance), a spice market, a hand-drawn portrait studio, and themed drinks that all tied back to the whimsy and wonder that pulse through the heart of the series.
