Sprinkled among all the special-effects heavy blockbuster hopefuls due to be released this summer, the most controversial film of the summer season could be a documentary on religion.

Television commentator Bill Maher, no stranger to controversy, has teamed with Larry Charles, the director of "Borat: Cultural Learnings Of America For Make Benefit Glorious Nation of Kazakhstan," to make "Religulous", a documentary due out in June featuring Maher's POV on the sensitive topic. The two traveled all over the world to research and interview people about God and and faith.

"Comedically, the topic of religion is hitting the side of a barn;" Maher told the industry trade Daily Variety. "It's literally hard to miss. This movie will make you laugh so hard you'll pray for it to stop."

Lionsgate will release "Religulous" June 20th. If early reaction is any indication, the film could touch off heated debate. Religion, like politics, is one of those topics that always invites passionate, sometimes irrational responses. The idea of mixing religion and comedy in general sounds like a potentially volatile mix. Many other comics have been doing it for years, like George Carlin. It will be interesting to see how Maher's take on it comes across.
