Christopher Nolan's 2010 cerebral heist flick follows a team led by Dom Cobb (Leonardo DiCaprio) that specializes in infiltrating people's minds as they sleep in order to find information. Dom and his group, including Arthur (Joseph Gordon-Levitt) and Ariadne (Ellen Page), are tasked with going into the brain of the heir of a powerful businessman (Cillian Murphy) and convincing him to break up his company. Mind-bending visuals (and many layers of inception to try to keep track of) ensue, and viewers are still debating the meaning of the ending.
Nolan's films often feature some of the same actors, and "Inception" actors Gordon-Levitt, Marion Cotillard, Tom Hardy, Cillian Murphy, and Michael Caine all appeared in his "Batman" series.
