Hans and Margret Rey are the subjects of MONKEY BUSINESS: THE ADVENTURES OF CURIOUS GEORGE'S CREATORS. Both born into affluent Jewish families in Germany and having lived an adventurous young adulthood that took them to France, Brazil, and back again to Paris, Hans and Margret made a desperate escape on bicycles to safety in early 1940. Having fled from the scourge of Nazism, the devoted husband and wife, who had no children of their own, ultimately made their way to the United States. There, Curious George became their "son." Filmmaker Ema Ryan Yamazaki's research, interviews with the Reys' longtime Waterville, New Hampshire, neighbors, and lots of footage of Hans and Margret themselves celebrates the couple, their courage, and their uniqueness. A loving, guileless genius, Hans opened his arms to the children of Waterville and those children, now well into adulthood, have wondrous memories of him. Margret, who was far less warm and fuzzy, but no less accomplished, is remembered for her feistiness, her devotion to Hans, and her savvy. The two lived long, prosperous, and creatively satisfying lives. This movie, which is narrated with spirit and warmth by Sam Waterston, commemorates those lives.
