First of all this the ground 0 for everything piracy (and more, generally free stuff) https://fmhy.net/

Here are the recommended film sites https://fmhy.net/video#torrent-sites

I generally download from https://rutracker.org/ (need an account to search not for downloading). They have pretty much everything that you can imagine (not just films) and in proper quality too (BD Remuxes etc). There will be no scene releases here because they add russian/ukrainian dubs and subs to almost all films but that's a small problem.

The other one is Heartive which lists torrents from the DHT network with Magnet links https://heartiveloves.pages.dev/ You just click on the torrent icon in the middle top of the selected film and all the available releases will be listed in plain text. The only downside that you need to be familiar with the release tags

Last but not least https://nyaa.si/ if you have a slight interest in anything japanese from manga to anime to much more
