Svoy sredi chuzhikh, chuzhoy sredi svoikh

Should really be recognized as a Western classic, or at least world's best "Eastern" - Mikhalkov follows the rules of the genre impeccably, easily weaving in 1920's Russia setting, revolutionary romanticism and "cool" charismatic bad guys, a rare thing in Soviet cinema. Cast is superb - probably the best combination of young actors of the decade, including Mikhalkov himself as Yesaul.
