What metaphors are used in The Empty Space by Peter Brook?

The cinema can be seen as a metaphor for theater. The author contends that cinema is akin to the theatre in many ways, in that both present active narratives of the human experience. The main contrast between the two, he suggests, is that theatre is immediate—the human beings on the stage are living an experience. In film, he writes, the images are those of the past (see "section seven, Summary and Analysis").
