"The adaptation of the classic Dutch children’s book ‘How to become king’ by Jan Terlouw has turned into a spectacular success, of the type rarely found in the world of children’s cinema. Aside from getting absorbed in the mythical Katoren-world, the movie has enough depth to appeal to adult viewers."

"‘To Be King’ is an adventurous film for kids with a charismatic lead. A classic story that stand the test of time thanks to it’s modern adaptation."
- Shelley Eimers - Cinemagazine -

"Fans of the original book should rejoice. Despite the many changes, Sombogaart’s adaptation is daring and has a voice of it’s own. A well made Dutch adventure that distinguishes itself from the uniformity of Hollywood."
