Production

In 1950, Ray had decided that Pather Panchali, the classic coming of age story (bildungsroman) of Bengali literature, published in 1928 by Bibhutibhusan Bandopadhyay, would be the subject matter for his first film. This semi-autobiographical novel describes the growing up of Apu, a small boy in a Bengal village. He went ahead with the film after meeting Jean Renoir during filming of The River (1951) and after watching the Italian neorealist film Bicycle Thieves (1948) while he was in London. Besides the influence of European cinema and Bengali literature, Ray is also indebted to the Indian theatrical tradition, particularly the rasa theory of classical Sanskrit drama. The complicated doctrine of rasa centers predominantly on feelings experienced not only by the characters but also conveyed in a certain artistic way to the spectator. The duality of rasa representation shows in The Apu Trilogy.

Ray gathered an inexperienced crew, although both his cameraman Subrata Mitra and art director Bansi Chandragupta went on to achieve great acclaim. The cast consisted of mostly amateur artists. Shooting started in late 1952, using Ray's personal savings. He had hoped that once the initial shots had been completed, he would be able to obtain funds to support the project, but such funding was not forthcoming. Pather Panchali was shot over the unusually long period of three years, because shooting was possible only from time to time, when Ray or production manager Anil Chowdhury could arrange further money. With a loan from the West Bengal government, the film was finally completed and released in 1955 to great critical and popular success, sweeping up numerous prizes and having long runs in both India and abroad. During the making of the film, Ray refused funding from sources who demanded a change in script or the supervision of the producer, and he ignored advice from the government (which finally funded the film anyway) to incorporate a happy ending in having Apu's family join a "development project". Even greater help than Renoir's encouragement occurred when Ray showed a sequence to John Huston who was in India scouting locations for The Man Who Would Be King. The sequence is the remarkable vision Apu and his sister have of the train running through the countryside. It was the only sequence Ray had filmed due to his small budget. Huston praised Ray to Monroe Wheeler at the New York Museum of Modern Art, saying that a major talent was on the horizon. In India, the reaction to the film was enthusiastic; The Times of India wrote that "it is absurd to compare it with any other Indian cinema. Pather Panchali is pure cinema". In the United Kingdom, Lindsay Anderson wrote a glowing review of the film. However, the reaction was not uniformly positive. After watching the film, François Truffaut is reported to have said, "I don't want to see a movie of peasants eating with their hands". Bosley Crowther, then the most influential critic of The New York Times, wrote a mixed review of the film that its distributor Ed Harrison thought would kill off the film when it got released in the United States, but it enjoyed an exceptionally long run.

Ray's international career started in earnest after the success of his next film, Aparajito (The Unvanquished). This film shows the eternal struggle between the ambitions of Apu as a young man and the mother who loves him. Some critics, notably Mrinal Sen and Ritwik Ghatak, rank it even higher than the first film. Aparajito won the Golden Lion at the Venice Film Festival. The film is also notable for its application of bounce lighting to recreate the effect of daylight on sets with the use of large scale diffusers, pioneered by the cinematographer Subrata Mitra.

Ray had not thought about a trilogy while making Aparajito, and it occurred to him only after being asked about the idea in Venice. The final installation of the series, Apur Sansar (The World of Apu), was made in 1959. A number of critics find this to be the supreme achievement of the trilogy (Robin Wood, Aparna Sen). Ray introduced two of his favourite actors, Soumitra Chatterjee and Sharmila Tagore, in this film. The film finds Apu living in a nondescript Kolkata house in near-poverty. He becomes involved in an unusual marriage with Aparna, the scenes of their life together forming "one of the cinema's classic affirmative depiction of married life", but tragedy ensues. After Apur Sansar was harshly criticised by a Bengali critic, Ray wrote an article defending it—a rare event in Ray's filmmaking career (the other major instance involved the film Charulata, Ray's personal favourite). His success had little influence on his personal life in the years to come. Ray continued to live with his mother, uncle and other members of his extended family in a rented house.
