Even though set in 1965 several of the actors are wearing clothes in typical 1980's style.
The troops guarding Manteuffel's lab at the beginning of the film are improperly uniformed. They wear the Nazi party swastika armbands although they are clearly wearing Wehrmacht army uniforms. The armband was only worn by SS troops and Nazi officials and, by this point in the war, only with full dress uniforms and not in the field.
