David Cho

In a departure from his previous films which blended finely-observed realism and light romance, Cho's Planck Constant (2015) contained more surrealistic and fantasy elements, with Kim Jae-wook playing a man who gets his hair cut 1 millimeter a day, while writing a screenplay in his head.

In 2014, Cho cast Lee Sang-yoon and Yoon Jin-seo in his fourth film Santa Barbara (2014). They played, respectively, a music director and a creative director at an advertising agency who fall in love while collaborating on a commercial; after their break-up, they are forced to work together again on a project in Santa Barbara, California, the location of their dream winery tour when they were still a couple.

Also released in 2012, Cho's third film The Winter of the Year Was Warm focuses on a Seoul-based film producer/director who's fond of the laidback atmosphere in the coastal city of Gangneung, and a nurse who lives in Gangneung but yearns for the cultural life of Seoul; after meeting through a common friend, they each agree to set aside one room in their respective apartments for the other to stay at on weekends, but in sharing their homes with each other, they eventually start to develop a strange sort of in absentia intimacy. The film drew critical acclaim when it premiered at the 17th Busan International Film Festival and as it traveled the international film festival circuit, with particular praise for Cho's nuanced script and use of lighting, as well as Kim Tae-woo and Ye Ji-won's naturalistic acting.

In 2010, Cho made his directorial debut with Second Half starring Ryu Seung-soo and Esom, about a beleaguered film producer who meets a waitress in a seaside town and suspects she may be his daughter from a long-ago one-night stand. Cho's second film The Heaven Is Only Open to the Single! (2012) is about a famous actress (played by Choi Yoon-so) who's just been publicly dumped by a comedian and banned by her agency from dating, and an unknown indie musician rejected by a matchmaking service who falls for her onscreen while composing the soundtrack for her film. With a cast of real-life Hongdae musicians led by Lee Neung-ryong of the band Sister's Barbershop, Cho interspersed live musical performances into the film.
