It’s no secret that Bill Maher, the host of the HBO show "Real Time with Bill Maher," loathes religion. He came under fire earlier this year for slandering Pope Benedict XVI.

On Tuesday night, CNN’s Larry King gave Maher another chance to smack Christianity, which Maher called “detrimental” and “the ultimate hustle.”

 Maher was on "Larry King Live"  to promote his latest vehicle, the film "Religulous," which is due to open October 3. "Religulous," which reportedly takes aim at all religions, was supposed to be released around Easter of this year.  It had been called a documentary previously but Maher is now selling it as a comedy.  Larry King opened his interview with Maher by praising the movie but noted that it will offend people.
