'Fantasy Railroad in the Stars (銀河鉄道の夜)' by Kagaya Studio

Gallary of screen captures

In spite of the fact that the original short story by Miyazawa Kenji 宮沢賢治 has human characters, you will not encounter a human face in this anime adaptation by Kagaya Studio, which attempts to tell the story with a 45-minute sequence of still-lifes.

Having said that, every frame in this anime is of poster quality, so it should not be a great problem for the audience to sustain interest in spite of the lack of drama involving human interactions. (But to be honest, since I have an extremely short attention span, I could not help but wish at times that I could get it over with by fast-forwarding... Still, one has to give them points just for trying...)
