An anime director was asked to direct an anime movie. But it was learned that director doesn't really direct anime. Why is that person hired?
Can I ask, why do you want to know? Why does it matter to you?
I'm just curious, because you seem very fixated on a particular train of thought in regards to anime and anthologies.
Yeah, it just seems a bit strange that a) it's just random and b) you could search some of this stuff up on google.
The technicality required for producing a feature length movie differ from comics and serialized animation. Very few have the skill sets and drive for working in both mediums.
