We have also written extensive behind-the-scenes articles. You can find articles about the pre-production and filming, the editing and color grading and last a long post about the VFX and 3D animations.

All of the articles are available in English and German.
For now, my own blog will be written in English, but if there ever is the need to localize it into German, I can do it.
