Dom Cobb (Leonardo DiCaprio) and his partner Arthur (Joseph Gordon-Levitt) perform illegal corporate espionage by entering the subconscious minds of their targets, using two-level "dream within a dream" strategies to "extract" valuable information. "Start" finally transforms Nolan into one of the most amazing directors working today, and for those who are conducting his career brilliantly. Every time he gives Hollywood a pound of flesh in the form of a huge comic hit, he demands that she compensate him for it in the form of funding for a film with such a convoluted script that there is no chance that the audience (or even the average studio director) will be able to understand who is against whom. And so, in fact, his career is a sort of flicker of movies: after "Batman Begins" he brought the "luxury". After the "Dark Knight" is brought to the "start". And because Warner Bros. agreed to pay him the "start" - a film I would be very surprised if he would cover his cost at the box office - he agreed to commit to directing a third Batman movie. It would be interesting to see what he would do after that. So that in fact Nolan's career is divided into two: the action films he makes at the studios, and those of the films he initiated and wrote himself. "Begin" therefore continues the line that was born in "Mantu" and "prestige", and he even continues the ideas that he started there, and especially the question: What is the reality? In "Memento", "prestige" and "start" the hero needs, almost At any moment, stop and ask himself what truth and what lie, or what a deception, or a dream. Nolan, a witty director like him, makes brilliant use of the cinematic medium, since these questions - what is real and what is false - are an inseparable part of the film's viewing experience. Cobb's totem is a spinning top which spins perpetually in the dream state. Cobb struggles with memories of his dead wife Mal (Marion Cotillard) that manifest within the dream and try to sabotage his efforts.
