After The Return which won several awards in 2018, such as the European Jury Prize in Brussels and a Special Mention from Rotterdam’s Bright Future competition strand, Choi goes back to the theme of adoption, and teams up again with co-writer Sisse Dalsgaard Thomsen.

The story centres on South-Korean-born Carl who lives a quiet life in the countryside with his adoptive parents, the farmers Karen and Hans. The couple expect their son to take over the farming business, but Carl has other dreams and aspirations: he wants to find his home and reconnect with his own roots.

Choi who herself was adopted from South Korea said: "The Quiet Migration revolves around ‘the bond of blood and family' and 'belonging and not belonging' as we adoptees experience trying to find ourselves and our place in the adoptive family. We have been quiet about our lives in adoptive families; not everyone has been prepared to become a multicultural family when adopting a foreign child, and you don't bite the hand that feeds you. But I would argue that we live as a hidden minority despite having a more privileged status than other migrants, but we are also more vulnerable because we came alone - [hence the title] the quiet migration. “My intention is to make our hidden lives visible and show from an insider's perspective some of the unforeseen consequences that this habitual form of migration creates," she said.

Bjarne Henriksen, who played the social worker Lars Madsen in DR Drama’s acclaimed series Cry Wolf, is cast as farmer Hans, and his wife Karen is played by seasoned actress Bodil Jørgensen (Nothing’s All Bad, The Idiots, The Kingdom). Making his debut as the adopted son Carl is Cornelius Won Riedel-Clausen. Other actors include Anders Baggesen, Lene Poulsen, Claus Flygare, Ole Boisen, Vigga Bro, and Johan Hermann.

Crew members take in production designer Josephine Farsø (Cry Wolf, Holiday) and cinematographer Louise Maclaughlin (The Good Traitor, The Chestnut Man)

The DKK 11 million (€1.5m) film is produced by Maria Møller Kjeldgaard for Manna Film, with backing from DR, the West Danish Film Fund and Nordisk Film & TV Fond.

Filming is underway in Denmark for another two weeks, and a second unit will be shooting in South Korea two days in October.

The national release scheduled for late spring/summer 2022, will be handled by Øst for Paradis in Denmark, while Mer Film will oversee the Norwegian release.​
