The very first Harry Potter movie opened 15 years ago next month. Fifteen years. A lot has changed in blockbuster movies over the past decade and a half – superheroes are now front and center, CG has advanced to remarkable degrees, and remakes, prequels and spin-offs are filling the movie theaters. But J.K. Rowling’s magical world was one of the most original series of its time. Before Harry Potter and the Sorcerer’s Stone opened on November 18, 2001, the only major movies for kids born in the ‘80s and ‘90s were animated films from Disney and Dreamworks. The 21st Century also brought with it the Star Wars prequels and the Lord of the Rings series, but Harry Potter introduced a whole new era of fantasy blockbusters for kids (Chronicles of Narnia, The Golden Compass, Twilight, etc.). It gave millennials the first major family franchise of their generation.
