I got a message about how to get, and watch the films. This is not hard, but it's something that takes a bit of experience. Here is what you need to do, in broad terms.

Download and install a player. Recommended as easiest to use, and free: Media Player Classic MPC-HC: Media Player Classic Home Cinema download | SourceForge.net or VLC VideoLAN - Download official VLC media player for Windows.

Download the film using a bittorrent client such as qbittorrent after searching for it on rutracker.org (you will first have to create an account on Rutracker).
If you do not know how to use bittorrent, google for a generic guide. If this seems too hard, forget this and use Youtube...

When you have downloaded the film, download the subtitle and extract the files from the Zip archive into the same directory as the film.
Rename the subtitle to the same as the film.

Playing the film:
VLC does the below more or less automatically. However Media player classic has some usability advantages in other areas.
It will automatically load any subtitles that are named the same as the film.
To see subtitles in Media player classic, make sure settings are on Menu: View>Options>Output. Select "Video Mixing Renderer 7 or 9 - Renderless) Make sure you enable Subtitles: Rightclick on the screen and select Subtitles>Enabled.

The principle to show subtitles is: Ensure all settings to actually show the subtitles are enabled. Subtitles usually have the file extension .srt or .sub.

If the subtitles seem to be out of sync: Check that you have the right version of the film. Some films have a "director's cut" version which is longer than the regular film. Alternatively the Blueray version is sometimes different than the DVD version.Older Russian films have often been restored including some cutting. Did you get the subtitles for a complete film where the film you actually downloaded is the 2 CD version, or vice versa?
Should it be totally impossible to find a match, there are editors which will let you shift all the subtitles forward or back to match the film.
You can also ask for help in Rutrackers forum (in Russian), alternatively here in either language.
