1997’s Cube by Vincenzo Natali.
I’m a big fan of this movie.
While some movies are applauded based on their soundtrack, I love how this movie plays so well without a score. Instead tense moments are marked with silence or diegetic sounds.
The characters are introduced with just enough to get them going, but that allows the audience and other characters to learn more about them as time goes on revealing interesting facts and oddities.
Honestly I don’t want to give too much away. It’s not a jump-scare kind of movie, but more of a tense and suspense kind of movie. Give it a watch sometime and I hope you enjoy it.
