What is Life? The Movie is a feature-length (1 hour and 30 minute) documentary that viewers have called a cross between "What the Bleep?", "My Dinner with Andre", and Woody Allen. The film explores the big questions in life for which there are no clear answers, such as: Is there a God? What is the nature of the soul? How does one attain meaning in one's life? Why is there evil? Is there such a thing as destiny? Dr. Weiner, who serves as the host, tackles these questions with a mixture of philosophy and humor.

The film interviews over 35 different people. Filmed over a four year period in the United States, Israel, Brazil, Japan, China, Hungary, Vietnam, South Korea, and the Czech Republic, the film consists of fascinating answers provided by religious figures, philosophers, physicists and other experts, interspersed with equally thoughtful - and often hilarious - responses from ordinary people of all ages and from different cultures. Often, some of the most thoughtful and provocative answers come from non-experts.
