In Train to Busan, an overworked hedge-fund manager (Gong Yoo) and his young daughter (Kim Su-an) board a train to Busan, fighting many zombified passengers along the way. Yes, it's a zombie film, but like Parasite, the movie really shows how disparageing and selfish the rich can be toward the poor, especially through the character Yon-suk (Kim Eui-sung).
