In 1968, Miller attended the Democratic National Convention as a delegate for Eugene McCarthy. In 1969, Miller's works were banned in the Soviet Union after he campaigned for the freedom of dissident writers. Throughout the 1970s, Miller spent much of his time experimenting with the theatre, producing one-act plays such as "Fame" and "The Reason Why", and traveling with his wife, producing "In the Country" and "Chinese Encounters" with her. Both his 1972 comedy "The Creation of the World and Other Business" and its musical adaptation, "Up from Paradise", were critical and commercial failures.
