I don't know if this is the right place for what I'm looking for.

I was recommended to come to this forum, where I might find what I'm looking for.

I'm looking for torrent sites or some other way to download new and not-so-new 4K remux movies. I just discovered the Plex app and I think it's incredible—watching your own movies at the highest bit rate possible. I want to get the most out of my LG OLED TV with HDR and all kinds of other technologies.

What I'm looking for is exclusively movies in English and Latin American Spanish, those two languages ​​only.

If anyone can give me a guide on how to do this, please help.
