Kim handed Byun the scenario himself.[16](https://www.ajunews.com/view/20170622145128663) • [17](https://v.daum.net/v/20170611152932840) Kim described the role as difficult because the subtle emotional shifts across each loop iteration had to be performed out of sequence, with scenes grouped by location within a fixed shooting period.[7](https://v.daum.net/v/20170617115009533)\n\n**Shooting.** Filming began on June 29, 2016 at Songdo Central Park in Incheon and finished on September 29, 2016, after three months.[1](https://asianwiki.com/index.php?title=A_Day_%28Movie%29) • [18](https://enews.imbc.com/News/RetrieveNewsInfo/191766) Jo deliberately set the tragedy on a bright, cloudless summer day, reasoning that a peaceful everyday setting would make the catastrophe more painful; the crew worked through heat above 35 degrees Celsius.[19](https://www.koreafilm.co.kr/movie/aday/aday_2-1.htm) To keep the loop's causality consistent, the director and staff calculated each character's movements minute by minute.[15](https://sports.khan.co.kr/article/201706191803003) The score by Mowg runs against thriller convention, using bright, light music to heighten the contrast with the film's grim events.[20](https://sports.donga.com/ent/article/all/20170623/85024367/1)\n\n## Release and box office\n\nA Day opened in South Korea on June 15, 2017 on 781 screens.[6](https://m.koreanfilm.or.kr/eng/films/index/filmsView.jsp?movieCd=20166384) It took first place at the daily box office on its opening day with 77,974 admissions, ending the nine-day run of *The Mummy* at number one, a result Korean media noted as an uncommon win for a domestic film against Hollywood releases.[4](https://v.daum.net/v/20170616064433678) It went on to 1,129,609 total admissions and a gross of $6,733,515, against a production budget of about 6.2 billion won.[6](https://m.koreanfilm.or.kr/eng/films/index/filmsView.jsp?movieCd=20166384) • [7](https://v.daum.net/v/20170617115009533)\n\nThe film circulated widely on the festival circuit in 2017: it premiered at the Busan International Film Festival and later screened at Sitges, Fantasia in Montreal, and L'Étrange Festival in Paris, where it was described as a thriller take on *Groundhog Day* that plays with the genre's rules.[10](https://www.cinematheque.co.kr/cinema/20166384) • [21](https://brunch.co.kr/%40slist/639) • [22](https://www.etrangefestival.com//2017/en/film/ha_roo) It was later made available on streaming services including Netflix, Apple TV, and Viu in various markets.[23](https://www.netflix.com/kr/title/81131736) • [24](https://www.viu.com/ott/id/articles/sinopsis-a-day/)\n\n## Reception\n\n**Critical response.** On the Rotten Tomatoes Tomatometer the film holds 100% from 7 reviews with an average rating of 8.5.[2](https://tv.apple.com/kr/movie/%E1%84%92%E1%85%A1%E1%84%85%E1%85%AE/umc.cmc.5mobqb2lv0tvfiidd0sgb97fc) Wendy Ide, senior international critic for *Screen*, reviewing at the Macao festival, called it an \"ambitiously high concept thriller\" with a baffling timeline that deft editing mostly keeps coherent, praising the action sequences while criticizing an overbearing score and some strident performances.[9](https://www.screendaily.com/reviews/a-day-macao-review/5124955.article) Korean critics were more divided: Cine21's three reviewers scored it between 4 and 5 out of 10, and a Star News review found the mystery resolved by showing rather than letting the audience deduce.[3](https://cine21.com/movie/info/?movie_id=48484) • [25](https://www.starnewskorea.com/movie/2017/06/16/2017061608181688953) The Korean Association of Film Critics gave the film its screenplay award that year.[10](https://www.cinematheque.co.kr/cinema/20166384)\n\n**The time-loop device.** Korean coverage emphasized how rarely the loop structure had been used in domestic cinema, citing precedents such as *Groundhog Day*, *Source Code*, and *Edge of Tomorrow*.[25](https://www.starnewskorea.com/movie/2017/06/16/2017061608181688953) • [13](https://star.ohmynews.com/NWS_Web/OhmyStar/at_pg.aspx?CNTN_CD=A0002333011) Jo argued that the loop is a tool rather than the point: the film's core, in his account and in Kim Myung-min's, is family love, the story of three men trying to save the people they lost.[15](https://sports.khan.co.kr/article/201706191803003) • [7](https://v.daum.net/v/20170617115009533) The two leads embody contrasting responses to the same trap, Jun-young working the problem intellectually while Min-chul throws himself bodily at it, a contrast the director used to drive the film's pace.[7](https://v.daum.net/v/20170617115009533) • [16](https://www.ajunews.com/view/20170622145128663)\n\n## References\n\n1.
