According to Screen Daily the Vinyan and Calvaire director will soon be bringing us Alleluia, which will be based on the true story of two of the Forties’ most notorious serial killers — Martha Beck and Raymond Fernandez, also known as The Lonely Hearts Killers.
Thus far the incredibly spooky Béatrice Dalle (pictured; Inside) is set to star along with Bouli Lanners and Virginie Efira. Du Welz has co-written the script with Vincent Tavier, and shooting is now set for early 2011.
Raymond Fernandez and his common-law wife Martha Beck became known as “The Lonely Hearts Killers” after their arrest and trial for serial murder in 1949. Between 1947 and 1949 they are believed to have killed as many as 20 women. – as per WikiPedia
