Visible crew/equipment: When the Russian army rushes through to the Germans, you can see a camera crew briefly on the right. (00:13:30)
Visible crew/equipment: After it has been discovered Sacha is dead, Tania is arguing with Vassilli. He is trying to prevent her from running to him. The camera gets close to the action and the shadow of its operator is blatantly visible on the actors.
Chosen answer: Vasily Zaitsev (Jude Law) uses a 7.62 x 54mm Mosin-Nagant M91/30 rifle with a PU scope. Major König (Ed Harris) used a 7.92 x57mm Mauser Karabiner 98 K with scope. Law's scope was wrong as the model used in the film wasn't available until after the Battle of Stalingrad.
