The document discusses the character research for a film. The antagonist is based on Jack the Ripper, who was never caught, and the film uses an enigma code and avoids showing the antagonist's face to keep their identity a mystery. The two main inspirations for the protagonist are Patrick Bateman from American Psycho for his confident and intimidating personality, and Leonardo DiCaprio for portraying greedy characters. The protagonist will start confident but become less so when confronting the antagonist.
