This is how it’s done.
This is the book trailer for Kairos, a french graphic novel by Author/Illustrator Ulysse Malassagne. Animated by Studio La Cachette. This is a perfect example of two important points. The first point is hand-drawn animation is powerful and deeply engaging to the viewer on a level unique to itself. The second is this book trailer really piques your interest to read the graphic novel itself. Even though the graphic novel is a different medium from the trailer that is animated, it transcends and conveys the story so well that you very much want to go out and read it.
