I'll check it out most of these require an API key, which sucks cause it gets rate limited, plus we're building a parallel decentralized database anyway.
https://www.themoviedb.org/ has an API for automatically grabbing images and metadata for films. There is a similar TV project too. It's used by projects like Jellyfin, Kodi & Stremio.

First time I've seen this:
API is permissioned behind an API key, we don't care for permissions we build our own decentralized movie database
OMDB? (Not TMDB as Ryan mentioned)

It says it's creative commons. No idea tho
