Nice list. I 'm glad to realize that i've seen a lot of them. Layer Cake and A prophet would be on my top list.

Here are some other foreign mob movies i would recommend :

- Company (India) : a movie inspired by the story of the so called "D Company", considered to be India's biggest CO

- Une vie meilleure ("A better life"): a small budget French movie about the Corsican Mafia.

- GAL (Spain) : it tells the true story of how the Spanish secret services used French mobsters to kill Basque ETA members who were living in France.

- Anime Nere ("Black souls") : an Italian movie about a N'Drangheta clan. I've watched pretty much every Italian movies about the Mafia and i 'd say Anime Nere is among my favourites.

- Shottas (Jamaica) : it's about Jamaican gangsters in Jamaica and Florida.

- Yardie (UK): first movie directed by idriss Elba on a Jamaican gangster in the UK.
