In 2015, Anupama and Dutta started working on
Flickering Lights, a documentary about a village in Manipur awaiting electricity.
Nocturnes (2024) The idea for
Nocturnes began when Anirban Dutta and Anupama met Mansi by chance at a restaurant in the
western Himalayas. Mansi spoke passionately about her research on moths in the Eastern Himalayas. Intrigued by her stories and the beauty of the forest, Anirban and Anupama decided to change their plans and focus on making a film about Mansi's work with moths. The jury at Sundance said, "The images and sound in this film immediately invoke in the audience a meditative state as they enter the film's world, at the same time bringing a laser focus to the film's main subject. The confidence of the cinematography and sound design in building this story is part of its power and allure".
Nocturnes was also selected for the
MAMI Mumbai Film Festival 2024, where it competed in the South Asia Competition and won the Silver Gateway Award., as well as the
Thessaloniki Documentary Festival, where it won the WWF Award for Best Film in the Habitat Section. == Selected filmography ==
