Pairing political humorist Bill Maher and Borat director Larry Charles on a documentary about religion just sounds like you're asking for trouble or at the very least controversy. But trouble may be exactly what the new film Religulous wants to stir in the final weeks oging into the presidential election. Maher and Charles are self-described disbelievers who join forces to try and figure out why so many people are so blindly devoted to religion. Maher, raised by a Jewish mother and Catholic father, long ago renounced his faith in a higher being and now he wants to find out what makes other believe. Many may find his tone insulting and his approach one-sided but Maher is also consistently funny and provocative, and the documentary does raise questions about the role faith plays in our society. The trailer is courtesy of Lionsgate and is scheduled to open on October 3.
