 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.
