Enemy At The Gates (2001)

Captivating WWII movie from 2001, starring Jude Law (Vassili Zaitev)), Joseph Fiennes (Danilov), Rachel Weisz (Tania) and Bob Hoskins (Kruschev). The story involves the sparring between a Russian and a German sniper on either side of the 1942 bloody Battle of Stalingrad, plus an undercurrent of Law and Fiennes sparring for the love of Tania. 'Inspired by a true story', which gives it an edge. 

IMDB 7.4/10
