Indian filmmaker Anuparna Roy has been carrying Ameena’s story since childhood.

Ameena was a bonded laborer in Roy’s hometown, and something she once said about her marriage stayed with the director long after she grew up and moved away. That memory became the seed for “Lovers in the Blue Night,” which premieres in the Horizons competition at the Venice Film Festival a year after Roy’s debut feature, “Songs of Forgotten Trees,” made her the first Indian filmmaker to win the section’s best director prize.

International sales on the new film are being handled by Parallax. A trailer has been unveiled.

Roy says “Songs of Forgotten Trees” was a personal story made under difficult funding conditions, built around two women who barely leave a single house. “Lovers in the Blue Night” widens that frame to four migrants moving through Mumbai; she also describes the production itself as far more professional this time, with deadlines and limitations she is still learning to work inside.

Asked whether she expected the new film to move into Venice’s main competition rather in Horizons, Roy says she dreamed of it rather than expected it, and that landing in the section again is no disappointment. She still considers herself a new director learning her craft alongside filmmakers she admires.
