Warzone / Movie:  Battle of Stalingrad (1942-43), as seen in Enemy At The Gates (2001)

Level Of Heat: Quite the opposite.  Warmth is conspicuously lacking both in the numbing cold of the Russian winter and the unyielding slog of a siege that would leave first the Soviets, and then the Nazis, at breaking point.

No wonder the film's heros are snipers Vassili Zaitsev (Jude Law) and Erwin Konig (Ed Harris) - guys who can snuggle under a blanket and wage their war from a position of relative comfort.

Has It Cooled Down Since?  In terms of buzz, it's heated up, says visitvolgograd.info, possibly as a result of the name change. 

"Volgograd is a major tourist center. It is a monument-city and a hero-city, visited by hundreds of thousands of Russian and foreign tourists.

They are attracted by Volgagrad's nature, mineral springs, spas and rest-houses, along with the rich and glorious history. There are many museums and monuments, with a vibrant culture and architecture."
