The movie Inception is a metaphor for creating a movie. Every member of the group has their own specific role that corresponds to that of the members of a film crew. Eames (Tom Hardy) is the actor who changes his appearance with ease; Ariadne (Ellen Page) writes the scenes; Mr. Saito (Ken Watanabe) is the studio director who pays for the project; Yusuf (Dileep Rao) is responsible for the special effects; Arthur (Joseph Gordon-Levitt) is the artistic director who helps bring the film’s concepts to life; Cobb (Leonardo DiCaprio) is the director — the only person who knows how everything should end. The group’s purpose is to implant an idea in someone’s head. Think about it — isn’t this the true purpose of any movie?
