Why would a scientist create a weapon of mass destruction that was capable of destroying the planet and ending life as we know it? J. Robert Oppenheimer, the theoretical physicist who led the Manhattan project and is known as the “father of the atomic bomb,” would later become guilt-ridden over his invention but his original intention was altogether different. He wanted to create a weapon so powerful and dangerous that it would intimidate all world leaders into putting an end to war but, of course, that idealistic concept ended in failure because human beings are flawed creatures. This same scenario is mirrored in the Czech sci-fi drama, Krakatit (1948), in which an engineer named Prokop (Karel Hoger) creates a powder that can become explosive and release atomic energy when activated by radio signals or other means. Like Oppenheimer, Prokop quickly comes to regret his discovery but a case of amnesia caused by an accidental explosion complicates the engineer’s desperate search for an associate, Jiri Tomes (Miroslav Homola), who stole the formula.
