During the editing of ‘Dolfje Weerwolfje’ the main character Dolf was found to need more facial expression in the scenes in which he was a werewolf. Certain subtleties in his expression were insufficiently visible. That is why Planet X FX, together with director Joram Lürsen and editor Peter Alderliesten, chose more than 130 shots in which they enhanced the emotions on Dolf’s face, so that specific moments in the film would be more meaningful.
In all shots, Dolf’s head was first stabilized. Then a grid which allows for the distortion of the underlying shot was placed over the inanimate face. Because this distortion can be animated, it was possible to move from one expression to the next at specific moments and within a certain period. The eyes, eyebrows, forehead, nose, ears and cheeks were given greater movement. Subtleties such as sighing, sniffing and pricking the ears were made possible and were applied in different degrees. In places where Dolf’s mouth had to be significantly adjusted, teeth were placed in the mouth. Here and there the synchronisation of the spoken text and the lip movements were improved.
On the night of his seventh birthday, the mild-mannered Dolf turns into a white, fuzzy werewolf. "What is going on?" he wonders. Dolf is confused and feels conflicted: he tries to cope with his new powers. They make him completely different at night, when he turns into a werewolf and loses his inhibitions, than during the day, when he is a shy schoolboy. Will he be able to accept his new identity?
