Maintaining the appearance of being a single, unbroken shot, A Record of Sweet murder is almost like a very bloody stage play. The real-time device brings to mind Hitchcock's Rope, with some cleverly hidden edits and sparing, but effective, special effects shots. The bulk of the movie really seems to happen all at once, drawing the viewer in to it's compelling and unusual story.
A Korean reporter brings a Japanese cameraman to meet a serial killer, who also happens to have once been a childhood friend. The killer traps them and, nervously wielding a knife, begins to explain that he needs them in order to enact some grander plan, an insane-sounding conspiracy theory. He explains that he needs them to wait for two other characters to show up, and when by some miracle they do, things start getting really crazy.
A Record of Sweet Murder has some fine performances, leaning into an odd, slightly surreal tone as it maintains its hyper real structure. This was something writer/director did very well in his horror classic Noroi: The Curse. While Sweet Murder is smaller in scope, it has a thematic energy, creates an interesting dialogue about fate and madness and the struggle between good and evil.
Found footage movies have a tendency to end abruptly or fall apart in the end and, thankfully, Sweet Murder brings it all back together and sticks the landing. A treat for foreign found footage fans and a thoughtful horror art film.
