If you loved The Call, try Seobok
A bridge between a film you've already seen and one most people haven't. Seobok has roughly 3.8× fewer votes than The Call — it's a deeper cut, not a mainstream recommendation. Here's what they share, and what the second one does that the first one doesn't.
What they share
Theyboth carry the paranoid mood tag, and they sit in Mystery / Science Fiction / Thriller territory. If that's the register that drew you to The Call, the second film will land in a comparable space — through a different lens.
What Seobok is
Rain-slicked highway, late autumn, a syringe glowing faintly on the passenger seat. A disgraced agent drives south with a pale young man in handcuffs who flinches at sunlight. Men in clean suits follow in silent cars. Like a Park Chan-wook thriller written by a sleep-deprived biochemist.
