During the filming of Harry Potter and the Sorcerer’s Stone, 10-year-old Emma Watson wasn’t simply pretending to write during Transfiguration class—she was actually dipping a quill into real ink and writing a personal note. Behind-the-scenes footage preserved by the Huntley Film Archives captured Watson practicing her handwriting at her desk while filming the iconic scene in which Harry and Ron arrive late to Professor McGonagall’s lesson. Despite how difficult feather quills can be to use, the young actress displayed impressively neat cursive handwriting for her age, adding an authentic and charming detail to the scene.
