Curious George is the most popular monkey in the world. Since its first publication in 1941, the beloved children’s book series has become a cultural phenomenon and sold over 75 million copies in over 25 languages. However, the story of Curios George’s creators, Hans and Margret Rey, remains largely unknown. The Reys were a husband and wife team, German Jewish refugees who escaped Nazi-occupied Europe on makeshift bicycles carrying the original Curious George manuscript. Using animation, archival materials, and interviews, Monkey Business: The Adventures of Curious George's Creators explores the extraordinary lives of the Reys, who were as curious and adventurous as George himself.
