Travers and Walt Disney himself, the Sherman brothers' story is rich with behind-the-scenes intrigue, creative breakthroughs, and quiet triumphs. Their work on Mary Poppins not only launched their careers―it transformed Disney's live-action division and influenced an entire era of musical filmmaking. Filled with never-before-published details, Making Mary Poppins is a story of art, ambition, and resilience.
