Satyajit Ray

He directed the Apu Trilogy (1955-1959), whose first film, Pather Panchali, won the Best Human Document prize at Cannes in 1956 and made him an internationally recognised filmmaker.

Aparajito won the Golden Lion at Venice in 1957, and in 1992 he received an honorary Academy Award for lifetime achievement and India's Bharat Ratna.

Besides directing, he wrote the Feluda detective stories and composed the music for his own films from Teen Kanya (1961) onward.

Unable to find a producer for Pather Panchali, he took a notebook of sketches, dialogue and treatment and a second sketchbook of key scenes to potential backers, and when none came forward he started shooting on Sundays with borrowed money.

This is consistent with a habit of preparing a film visually in advance and continuing through a funding gap rather than waiting for backing. Planning Orientation

From Teen Kanya (1961) he composed his own film scores, saying he had too many musical ideas of his own and that composers resented being guided; two classical composers who had scored his films accused him of excessive interference.

This is consistent with a strong need to control his own work, with a cost in friction with collaborators. Need for Autonomy

After Pather Panchali was screened at the Museum of Modern Art in 1955 and won at Cannes in 1956, he resigned from his job at the D. J. Keymer advertising agency and became a full-time filmmaker, making one or more films a year until 1983.

This is consistent with moving from a side project done around a day job to a sustained, prolific working life once the first film proved viable. Persistence
