I mistakenly bought tickets for the session with Danish subtitles in the Copenhagen Cinematek. Fun fact: I don´t speak Danish, nor Korean. So my impression about it is rather limited.
Cobweb is a comedy, the tale of a director trying to produce his masterpiece in the South Korea seventies. During the production, he has to manage actors, staff conflicts, censorship, and ghosts from the past. All situations presented in a light way.
Ultimately, it is a movie about movies and there are many opportunities during the film to nerd out about photography and production. Most of it takes place on a film set and there are several moments when you can enjoy this atmosphere. This happens, for example, in a very-well made and interesting climax scene.
Cobweb cast is high level. The main character is played by Song Kang-ho from Parasite, and there is some great acting from the supporting characters, especially Krystal Jang and Jeon Yeo-been, both performances won awards in Korea.
Overall, the movie is a nice, not pretentious comedy with a good story behind it. I was able to follow in spite of my language barrier. I absolutely recommend it, especially if you speak the language that it is being played in, and if you don´t, you can still watch it for the pure joy of the cinema.
