What is "agradoot"

Agradoot was a group of film technicians signing collectively as director, a phenomenon unique to Bengali cinema. The Agradoot core unit, formed in 1946, consisted initially of Bibhuti Laha (cameraman, 1915–1997), Jatin Datta (sound), Sailen Ghosal (lab work), Nitai Bhattacharya (scenarist) and Bimal Ghosh (production). The group was active up to the end of 1980s.
