you are missing the point. (proving yourself wrong?)
that movie has tons of AAA-grade creatives, AAA-grade actors, tens of thousands of people work, brand new music, licenced music, photos, drawings, videos, animations and motion graphics, 3D assets, pictures, photos, whole buildings and set built for this, that borderline tiny real towns. LotR had to develop brand new state-of-the-art VFX rendering tech, which is often the case with such projects.
VFX for say "fake" UI Iron Man suit, had to write tons of code to make it work. amount of work those movies and games take in creatives (very often it is just code) is unbelievable.
now, with this utility app. what did it produce? not even close.
