Waking Life is composed exclusively of a series of conversations involving the main character, with him sometimes participating and sometimes just as a spectator. The discussions revolve around issues such as metaphysics, free will, social philosophy or the meaning of life. The title refers to a quote from Jorge Santayana: "sanity is a madness put to good uses; waking life is a dream controlled.", and the whole movie wanders around the state of a lucid dream, emphasized by the rotoscoping technique in which it was filmed. Waking Life is not just a movie worth watching, it is a movie worth watching a thousand times, because you will always notice something that you have previously missed out.
