Martijn en de magiër (1979)

Martijn Vonk prefers to spend his time drawing and writing stories instead of helping in his parent's shop. When a film company arrives in town to shoot a medieval fantasy, Martijn is offered to play the lead by the overenthusiastic director, and his grandfather is cast as a wizard. Meanwhile, a real sorcerer from India arrives on the scene, searching for a magical gathering place on which a confrontation between good and evil must be held. Martijn befriends Michiel, a young boy who is being held captive by the dark sorcerer.
