HBO, with a nod to the popularity of nonfiction filmmaking, has carved out a special night for documentaries.

The network on Monday said it will regularly air documentaries, featuring debuts of new original films along with timely encores presentations, on Monday nights.

The programming will air year-round, and officially started with last week’s “The Case Against 8.” In addition to tonight’s debut of “112 Weddings” (pictured), other new documentary films include Kate Davis and David Heilbroner’s “The Newburgh Sting” (July 21), Valerie Veatch’s “Love Child” (July 28), Peter Kunhardt’s “Nixon by Nixon: In His Own Words” (Aug. 4), Jeremiah Zagar’s “Captivated: The Trials of Pamela Smart” (Aug. 18) and Ben Steele’s “Hunted: The War Against Gays in Russia” (fall).

With the exception of some of its high-profile original films airing on Saturdays and an attempt with “Enlightened” on Mondays a few years ago, HBO has pretty much stuck with Sunday as its signature night of programming, dating back to “The Sopranos.”
