"Frankenstein" is the name of the crazy scientist in the novel. He spliced many pieces of corpses into a "man" and activated it with lightning. Frankenstein has become a classic in the history of science fiction, and many fantasy films and television works often appear a replica of this monster.
The term "Frankenstein" was later used to refer to "stubborn people" or "humanoid monsters" and "creations out of control". In his memoir "Toad's oil", Kurosawa described producer Songjiang Yangyi as "very mysterious and strange" and a "Frankenstein man".
