Two plays written by Ray Bradbury for Norman Corwin based on the short stories "Forever And The Earth" and "The Great Conflagration Up At The Place." There is a bonus interview with Bradbury and Corwin.

"The best way to describe Norman Corwin is he was the greatest director, the greatest writer and the greatest producer in the history of radio. There was nobody like him. Nobody could touch what he did."

- Ray Bradbury
