KRAKATIT (1948)

A classic Czech sci-fi noir, Krakatit tells the story of Prokop, a brilliant chemist who invents a super explosive named Krakatit and, after a lab accident, suffers feverish hallucinations, struggling to recall his formula as spies and shadowy figures pursue him, all while grappling with his guilt and the terrifying power of his discovery, blurring reality with dreams in a surreal, pre-nuclear anxiety thriller.
