Tiger I
The film was shot in the United Kingdom, partly due to the availability of working World War II-era tanks. The film featured Tiger 131, the last surviving operational Tiger I, owned by The Tank Museum at Bovington, England. It was the first time since the film "They Were Not Divided" (1950) that a real Tiger tank was used on a film set. Tiger 131 is a very early model Tiger I tank, and externally it has some significant differences from later Tiger I models. In the last weeks of the war, some early model Tigers were used in last ditch defense efforts; one of Germany's last Tigers to be lost at the Brandenburg Gate in Berlin was of a similar vintage.
