Julien Lacombe and Pascal Sid's Behind the Walls - a title we've kept our eye on since early last year - has yielded a teaser trailer.
A period thriller with supernatural overtones, Walls was shot in 3D.
The film follows a young novelist lacking inspiration decides to isolate herself in the countryside to write her new book. As Suzanne discovers a sealed-up room in the basement of her house, she starts writing odd prose. Visions and nightmares soon strike her while the villagers grow worried as several little girls mysteriously disappear.
