I have posted before about the ways in which the titles of Korean movies are rendered in English: either the Korean name is retained (Silmido), or the English title is an exact or approximate translation of the Korean (Parasite), or the English title is more or less completely different (The host), or the Korean title is itself a transliteration of English (Oldboy).
I recently discovered the website koreanfilm.org, which I first assumed was an official site, but which turned out to be the private site of Darcy Paquet, now best known for his collaboration with director Bong Joon-Ho on the English subtitles for Parasite, assisted by a team of volunteer reviewers. The site gives the title of each movie in Korean and English, but otherwise refers to each by its English title. With some knowledge of Korean, the strategies I listed in the first paragraph can be seen. Sometimes the reviewer discusses the Korean title when it sheds some light on the meaning of the movie.
The champion in the ‘more different’ category is surely the 2004 movie 어디선가 누군가에 무슨일이 생기면 틀림없이 나타난다 홍반장 (eo-di-seon-ga nu-gun-ga-e mu-seun-il-i saeng-ki-myeon teul-rim-eob-shi na-ta-nan-da hong ban-jang), which is rendered in English as Mr Handy, or Mr Hong, or Mr Handy, Mr Hong, but which translates literally as If something happens to somebody somewhere, he always shows up, Chief Hong. This was the basis for the 2021 tv series Hometown Cha-cha-cha, which I mentioned here (in the PS at the end). ban-jang by itself usually translates as class monitor or class president at a school. Calling him Chief Hong makes it sound like he is the chief of police. Three major translation tools don’t even bother with the last word(s), Google giving If something happens to someone somewhere, it will definitely show up, Bing If something happens to someone anywhere, it will surely appear and Papago If something happens to someone, he will definitely appear.
