"House of Voices," the first feature film by Pascal Laugier, contains many of the elements that made his 2008 cult-classic "Martyrs" so great. Both films start off in a predictable, genre-specific way -- then gradually reveal darker, stranger, subterranean layers that defy our expectations. Of the two films, "House" is lighter fare, while "Martyrs" is far bloodier and much, much more disturbing.
"House of Voices," begins as a slow-build Gothic ghost-story, in the vein of 2007's "The Orphanage" or 2001's "The Others." "House" works quite well on this level, featuring engaging female performances, a slowly-unravelling mystery, some handsome cinematography, a lush dramatic score, and some moments of genuine dread. But then, in its final act, the film takes a sharp and surprising turn toward the surreal. I could describe what happens in these scenes, but what really makes them work is the way they're filmed -- the simple strange visual power of these moments. Suffice to say, while you might have a general idea where the plot of this movie is headed, you will probably not foresee exactly how it arrives there.
The final scenes of this movie plumb some nightmarish depths, departing stylistically from the subtle Gothic-horror which came before, and entering far stranger territory. Don't worry; it all adds up. This isn't one of those horror films which leads you on, only to end with such strangeness that you have no hope of understanding what the movie was about. No, everything here makes sense in terms of the film's plot. It's just that the film's sudden stylistic change is jarring and surreal, evoking the kinds of unexpected shifts we might experience in our deepest nightmares.
For me, this movie worked quite well. I see some others here have given it bad reviews. I gather that's because they don't know how to tell a thoughtful, well-made film from worthless pap like the "Saw" franchise. This certainly isn't the best movie I've ever seen, but it's a very fine, thoughtful, moderately scary film with a bizarre final act that might haunt you afterward.
If you like this film, and you have a strong stomach, I'd certainly recommend Laugier's "Martyrs." It plays the same stylistic tricks as this film, but much more intensely, and to greater effect. Word of warning, though: It is a far more disturbing film than "House of Voices."
