The film “Cast Iron” (1964) holds a distinct place in Otar Iosseliani’s body of work. Filmed at the Rustavi Metallurgical Plant, this documentary is far more than a mere piece of Soviet propaganda. While films of that era typically glorified heroic labor, Iosseliani transformed industrial chaos into poetry. He portrayed the metallurgical plant as a forge for tempering human character, where a silent bond among people is born through their struggle with fire.
