Alex Kendrick‘s Christian drama “Fireproof” shocked the box office this weekend. On 839 screens, the IDP/Samuel Goldwyn Films release grossed $6,804,764, the second-highest (after “Hannah Montana”) for any film released under 1,000 screens in 2008.  And while Iraq war-themed films have always found the box office a challenge, Neil Burger‘s “The Lucky Ones” was particularly disastrous, averaging just $431 on 425 screens.  On a sole screen at New York’s IFC Center, Matt Wolf‘s “Wild Combination” actually led the iW BOT -  which is ranked by per-theater average - grossing an impressive $11,850.
