Paddy Considine and Fares Fares (“Zero Dark Thirty”) are in negotiations to join the international ensemble of Summit Entertainment’s Soviet-era thriller “Child 44,” TheWrap has learned. The duo will be joining Tom Hardy, Noomi Rapace and Gary Oldman in the movie, which Daniel Espinosa (“Safe House”) is directing from a script by Richard Price, who adapted the bestselling novel by Tom Rob Smith. “The Killing” star Joel Kinnaman was previously reported to be in negotiations as well. Set during the 1950s, “Child 44” follows a member of the Soviet police (Hardy) who finds himself the target of his own government’s suspicions as he investigates a brutal serial killer targeting children. Fares will play one of Hardy’s trusted allies, while Considine’s role is being kept under wraps. Summit, which is owned by Lionsgate, partnered with Worldview Entertainment to co-finance and executive produce the movie earlier this year. Ridley Scott and Michael Schaefer will produce for Scott Free Productions along with Greg Shapiro. Lionsgate execs Erik Feig and Jim Miller will oversee the project for the studio. While “Child 44” is set in Russia, its cast will be primarily British (Hardy, Oldman, Considine) and Swedish (Rapace, Kinnaman, Fares).
