Alleluia, a gritty and gruesome genre-twister from Belgian director Fabrice Du Welz (Calvaire), was picked up by Music Box Films after a successful debut at the Cannes Film Festival. Based on the real-life murderous 1940s couple nicknamed the Lonely Hearts Killers, the film tells the story of a single mother (Lola Duenas) who falls hard for a gigolo and swindler (Laurent Lucas) and abandons everything—including her daughter—to join him in his schemes.

Alleluia is nothing short of an answered prayer for lovers of extreme cinema,” Music Box Films’ managing director Edward Arentz told Variety, which first reported the news. “After showcasing it at select North American film festivals this fall, we expect to open in theaters late this year or early next.”
