Bill Maher's anti-religion documentary Religulous is on track to become the highest-grossing documentary of the year by next Friday, the Los Angeles Times reported today (Wednesday). By last weekend, the film had already grossed more than $7 million in its first ten days at just 568 theaters. Ironically, the film is due to displace Expelled, Ben Stein's creationist documentary, which grossed $7.7 million during its domestic run earlier this year. (It opened at 1,052 theaters.) In reporting on the box-office success of the two films, the Times commented that it "just does to show that when it comes to religion and movies, the box office is agnostic."
