The official trailer for "The Unbelievers", a new film by Richard Dawkins and Lawrence Krauss was released today (February 8, 2013). It begins with a question:

Which is more important - to explain science or to destroy religion?

Dawkins and Krauss have traveled across the world with their message of science and reason, and the film documents their quest to establish lines of communication with people of diverse backgrounds. Interspersed with their first-hand experiences are interviews with several high profile Hollywood stars including Ricky Gervais, Woody Allen, Cameron Diaz and Sarah Silverman. It's clear that during the speaking tour Dawkins and Krauss engaged large audiences. It will certainly be interesting to see whether the film version generates similar enthusiasm. Although I'm not seeing much of a story here (more an extended PSA with many A-list cameos) I certainly hope that it does.
