The book “The Art of Leonardo DiCaprio” is written in a mixed literary style, scientific and artistic, using creative compositional techniques (notebook format, scientific analysis and parallel detective story). The fictional part of the book is a detective story in which Sherlock Holmes and Dr. Watson are investigating a case about a famous actor. The scientific part is presented in the form of a study dedicated to the creativity and acting skills of Leonardo DiCaprio. As a result of the study, a concept for analyzing acting skills, a system of categories and criteria for this analysis and means of acting expression, and a terminological dictionary of acting skills were formed.
