Waking Life is an American animated film directed by Richard Linklater and released in 2001. The film focuses on the nature of dreams, consciousness, and existentialism. The title is a reference to philosopher George Santayana's maxim: "Sanity is a madness put to good uses; waking life is a dream controlled."
The film was entirely rotoscoped, although it was shot using digital video of live actors with a team of artists drawing stylized lines and colors over each frame with computers, rather than being filmed and traced onto cels on a light box.
Ethan Hawke and Julie Delpy reprise their characters from Before Sunrise in one scene.
