This epic about Cossacks around the time of the Great War, Revolution and Russian Civil War was Bondarchuk's last project being posthumously finished by his son .A good deal of controversy surrounded this film which some of which surrounded the casting of Rupert Everett delayed its release by 15 years...I think from the photography on this clip which shows cossack cavalry charge entrenched Austrian artillery and machine guns it looks well worth tracking down.
