Pirate bay, search for "9 2009”. You can find it about 3/4 of the way down the page

You can search for "9 2009" to help finding it. Not on first page but does appear (check pm)

I typically get around this by adding the year.

so for this example, I would search "9 (2009)"

Use the IMDB ID for search in that instance.

The ID is the part of the URL that starts with “tt”. Lots of sites support that and for instances like that it’s the best bet. Do include the double t when searching.

Note: this works via API with jackett. It will probably work otherwise but worth trying the searcher plugins in qBittorrent using this method even without jackett.

Very unrelated. But I recall this being the first instance of trailers that I watched and was disappointed when the song in the trailer (Welcome Home by Coheed and Cambria) was not present in the movie at all.

This is like when I was trying to find music for the band "sex vid"

On some sites if you use the advanced search (ext.to for example), you can search by the IMDb ID.

good luck, I also have a strange affection for that movie

After a bit of searching on 1337x, I found a couple torrents whose screenshots seem to be from 9 (cgi burlap dolls) but 1337x is putting a cover image for some other movie called cloud 9 at the top of the description. The comments say the 1337x auto binding messed up.

For example, see the one listing that comes up for the exact search term "9 2009 1080p BDRip x265 DTS HD MA 5 1 Kira SEV" paying attention to the screenshots and comments.

4th search result on the 2nd try on iptorrents

haha been there, however I did succeed on finding it and it was either 1337x or ext.to
it sucks they don't have -term and "term" to refine search

I havent used those sites in a while, I have setup Arr stack for myself, but YTS was always my go-to in the past

radarr/prowlarr handle this plenty fine, no idea how they do it under the hood

I got that one, I think

Try rutracker and search for the director of the movie + 2009, you should find it
