It was indeed a long journey from India Film Industries to Kali Films and then to Technicians’ Studio. Priyanath Gangopadhyay was not satisfied even after forming the East India Studio when he severed ties with the Madans. Subsequently, he quit East India to form India Film Industries. This studio was located on the left-hand side of the road, if one walked a little ahead of the Tollygunje tram depot towards Karunamoyee. Gangopadhyay did not have the financial backing to build a full-fledged studio. Yet, he did not give up on his dreams. Instead, he started work and the first film was released in April of 1933. It was called Sabitri. The next production was Bilwamangal. It was released in December, 1933. 
Tragedy struck Gangopadhyay just when the affairs at the studio were starting to look bright. Son Kalidhan, who was preparing to go abroad, suddenly passed away in February 1934. It was in his memory that India Film Industries was named as Kali Films. Reenmukti, Taruni, Tulsidas and Patalpuri — came one after another. The likes of Jyotish Mukhopadhyay, Sushil Majumdar and Sukumar Dasgupta came to make films. Editor Jyotish Mukhopadhyay’s directorial debut happened at this studio. Of course, Gangopadhyay was already there. Along with Bengali films, Hindi (Modern Lady, Ashiana), Odiya (Prasha, Sitar Bibaha), Urdu (Amina), Tamil (Gul Bakawali) films were also made.
Kali Films was turned into a limited company in 1939. The next year, Gangopadhyay left Kolkata on health grounds after relinquishing his responsibility of running the studio. During his absence, Kali Films lost out on strengthening its home productions. The studio was mostly given out on rent to other productions. However, this did not continue for long and the studio had to down its shutters. An elderly Gangopadhyay had to get the High Court to intervene and regain his access to the studio. But the future of the studio became uncertain. That is when a few young technicians came forward. In 1951, Ashutosh Nag, Durgadas Mitra, Kalyan Maitra and Ramananda Sengupta jointly bought over the studio from the receiver. The property was renamed as Technicians’ Studio. Sound recordist Satyen Chattopadhyay joined in with assistants Debesh Ghosh and Mrinal Guhathakurta. Technicians’ Studio started its new journey thereafter.
The situation changed again in the 1970s. The expenses for electricity and other overheads led to a financial crisis. The amount of loans increased. The owner of the land on which the studio was built went to court. He wanted to evict the cinemawallahs. Answering the pleas of the technicians, the Left Front government took over the studio in 1979. It has been renovated by the TMC government and is still running well.
