Most of India's early talkies were shot in Bombay, which remains the leading production center, but sound filmmaking soon spread across the multilingual nation. Within just a few weeks of "Alam Ara"'s March 1931 premiere, the Calcutta-based Madan Pictures had released both the Hindi "Shirin Farhad" and the Bengali "Jamai Sasthi". The Hindustani "Heer Ranjha" was produced in Lahore, Punjab, the following year. In 1934, "Sati Sulochana", the first Kannada talking picture to be released, was shot in Kolhapur, Maharashtra; "Srinivasa Kalyanam" became the first Tamil talkie actually shot in Tamil Nadu. Once the first talkie features appeared, the conversion to full sound production happened as rapidly in India as it did in the United States. Already by 1932, the majority of feature productions were in sound; two years later, 164 of the 172 Indian feature films were talking pictures. Since 1934, with the sole exception of 1952, India has been among the top three movie-producing countries in the world every single year.
