Aldous Huxley’s 1932 dystopian classic gets a 21st century update. It imagines a utopian society — New London — that has achieved peace and stability through the banning of monogamy, privacy, money, family and history. But it’s on a collision course with the citizens of the brutal Savage Lands. The cast includes Alden Ehrenreich, Jessica Brown Findlay, Demi Moore and Harry Lloyd. (July 15, Peacock).
