Director David Yates described the script as an "interesting synthesis between a sort of political thriller and love story," noting that it's "a sort of fusion of genres." That aspect is hopefully what will differentiate this series from the original Harry Potter films.
"Fundamentally, it's a kind of love story, but it has a really interesting thriller-esque sort of vibe to it as well," he continued. "The thing about [J.K. Rowling's] books and movies, is they're always very generous. You know, they combined a number of genres. In one way, they're funny, they're emotional, they have a fantastical element, obviously. They can be quite dramatic. So, this movie is no exception. It's a really rich meal."
