Answer the following Q with stream of consciousness. Context: Mother India, its star Nargis, and the director Khan received many awards and nominations. Nargis won the Filmfare Best Actress Award in 1958 and became the first Indian to receive the Best Actress award at the Karlovy Vary International Film Festival in present-day Czech Republic. Mother India won the Filmfare Award for Best Film and scooped several other Filmfare awards including Best Director for Khan, Best Cinematographer for Faredoon Irani, and Best Sound for R. Kaushik. In 1958, the film became India's first submission for the Academy Award for Best Foreign Language Film and was chosen as one of the five nominations for the category. The international version, 120 minutes long, was sent for the Oscars. Additionally, this version had English subtitles, and dropped Mehboob Productions' logo, which featured the Communist hammer and sickle, to appease the Academy. The 120-minute version was later distributed in the US and UK by Columbia Pictures. The film came close to winning the Academy Award, but lost to Federico Fellini's Nights of Cabiria by a single vote. Khan was utterly disappointed at not winning the award. "He had seen the other films in the fray and believed Mother India was far superior to them" recalled Sunil Dutt years later. It also won two awards at the 5th National Film Awards in 1957: an All India Certificate of Merit for Best Feature Film and Certificate of Merit for Best Feature Film in Hindi.
