How Old Was Emma Watson in Half Blood Prince
In the end, the answer to "How old was Emma Watson in Half-Blood Prince?" is simple on paper: 16 to 17. But in the magic of film, she was the exact age she needed to be. She gave us a Hermione who was smart enough to save the world, but young enough to still believe in the power of a Christmas party invitation. So next time you rewatch the movie, raise your butterbeer to 16-year-old Emma. She carried the whole damn film on her shoulders, and she made it look easy. (Though I bet her mom was a nervous wreck.)
