Little Odessa is a good one.
Did you ever see Pay or Die (60's or so, with Ernest Borgnine); based on a true story (but it is the Italian-American mob--the roots of it).
never seen either one
besides eastern promises
the Russian enforcer character from the Wire "Boris.....why always Boris?"
the assumed Russian crime figures in 25th Hour
and the Russian crime figures of the last 2 editions of the martial arts series "Undisputed"
I've not seen any russian crime or related flicks
