Song Kang-ho deservedly won Best Actor at this spring’s Cannes Film Festival for his performance in writer/director Kore-eda’s latest bittersweet exploration of the de facto families we form across our lives. In Broker Song plays Sang-hyeon, who operates a black market business with his pal Dong-soo (Gang Dong-won), selling infants left at baby boxes to parents looking to adopt. But when one of the mothers, So-young (Lee Ji-eun), has second thoughts about surrendering her child, the men work with her to find a good home for the infant. Filming in South Korea for the first time, acclaimed Japanese auteur Kore-eda has crafted a road trip drama full of gentle observations about the ways in which we all sometimes feel abandoned—and how the search for home can be a perpetual quest.
