Christopher Isham

Partly adapted from cosmologist Stephen Hawking's popular book about his theories of the universe, this in-depth documentary also presents Hawking's daily life as he deals with the ALS that renders him virtually immobile and unable to speak without the use of a computer. Hawking's friends, family, former classmates and peers are interviewed about not only his theories but the man himself.

Christopher Isham discusses Gillo Pontecorvo's 'The Battle of Algiers' with Richard A. Clarke, former USA national coordinator for security and counterterrorism, and Michael A. Sheehan, former USA State Department coordinator for counterterrorism.
