This trilogy is considered by critics around the globe to rank among the greatest achievements of Indian film, and it is established as one of the most historically important cinematic debuts. "Pather Panchali" won at least thirteen international prizes (including Best Human Document at the 1956 Cannes Film Festival), followed by eleven international prizes for "Aparajito" (including the Golden Lion at the Venice Film Festival) and numerous other awards for "Apur Sansar" (including the Sutherland Trophy at the London Film Festival). When Ray made "Pather Panchali", he worked with a cast and crew most of whom had never been previously involved in film. Ray himself at the time of directing "Pather Panchali" had primarily worked in the advertising industry, although he had served as assistant director on Jean Renoir's 1951 film "The River". From this foundation, Ray went on to create other highly acclaimed films, like "Charulata", "Mahanagar", and "Aranyer Din Ratri", and his international success energised other Bengal filmmakers like Mrinal Sen and Ritwik Ghatak.
