During the last two days I watched Paradox Soldiers -- a Russian science fiction type film. Two men from Moscow and two Ukrainians go to a war reconstruction. There is some fist fighting, but because of an explosion they get sent back in time to the second world war.
The film must have been a sequel because two of the men knew what was happening and how to get back to the future. Also one of the men had a girl friend in this time, who he wanted to find. There was a lot of fighting in the World War II style, but dirty and ugly.
