The tanks used are original Soviet T-26, captured by the Finns during the Continuation War of 1941-44 and then used as the backbone of the Finnish tank forces. Several are in driving conditions in Finnish museums.
Although the film was a huge success in Finland, its production company National-Filmi Oy went bankrupt, because the international success was not as good as the production company expected.
All the airplanes seen in the movie were models that were flown by remote control.
Director Pekka Parikka insisted on having a red star painted on the tanks, although there was no insignia on the Russian tanks during the Winter War, just an identification number painted on the turret.
Most expensive film ever made in Finland (2006).
