This will be a list of a must watch movies about post soviet organized crime, mostly Russian but it will also show other ethnicity groups in the movies.
1. Racketeer;Rekitir (Рэкетир - 2007) This is the movie I find the most interesting from every movie I've watched, it doesn't show how Russians operate, but it does show a criminal group after the fall of USSR. It's decent if you want to get a general idea of how things work. But the traditions and w/e they show aren't Russian at all but Kazakhstan. The movie tells the story of a man named Sayan, that had to live through harsh 1990s and make tough decisions. There are some scenes from the movie in the spoiler. There is also movie Reketir 2 but I don't find it that interesting and it won't be listed in here as it's more a love story of a low street criminal and a girl of a businessman but it has a very big connection with the first movie.
2. Zhmurki (Жмурки - 2005) A comedy, of sort, about Russian crime in the '90s. If you get why it's funny for the most part, you're more than ready for Russian crime RP. In my opinion, this is a very good movie with a good story. Will add a trailer in the spoiler.
3. Brat 1 and 2. (Брат - 1997) Shows a conflict between a criminal group and their former contract killer. The second one doesn't focus on that, but it's still a good movie, so watch Brat 2 if you want to - I found it extremely good. I will post trailers of both movies in the spoiler.
4. Bumer (Бумер - 2003) Bumer is NOT about a criminal organization. I've seen 1321 people RPing their organization based on this film. Well, don't. It's just not about an organization, it's about 4 friends doing illegal activities to survive. It'll give you a good idea about living in the '90s, not how to RP as criminals)
5. Reshala. (Решала) Move is about modern day Russian crime, it shows a story of two brothers, one who's a street criminal that can be called ''gopnik'' or a street robber who gets drunk, does shit and doesn't really have a connections to a big organized crime group and his brother lawyer who's working on a Russian mafia.
