According to Deadline, the strong cast that director Daniel Espinosa assembled for Child 44 just got better. Philip Seymour Hoffman is negotiating to join Tom Hardy, Noomi Rapace, Gary Oldman, and Joel Kinnaman in the film. The picture is being made by Summit Entertainment and co-financed and executive produced by Worldview Entertainment. An adaptation of the Tom Rob Smith bestseller, the Richard Price-scripted Child 44 focuses on a member of the Soviet military police who investigates a series of nasty child murders during the Stalin-era Soviet Union. His biggest impediment is a government that refuses to acknowledge a serial killer is in their midst. Ridley Scott is producing under his Scott Free Productions banner with Michael Schaefer and Greg Shapiro. Hoffman joins the film mid-swing, as principal photography began June 10th in Prague.
