Safe House director Daniel Espinosa is filming an adaptation of Child 44, Tom Rob Smith's 2008 bestseller about a Stalin-era Soviet military police investigation into a series of child murders. The critically lauded book, the first in a trilogy Smith completed last year, is based on real-life serial killer Andrei Chikatilo. Espinosa and producer Ridley Scott have assembled a top-notch cast, as Philip Seymour Hoffman has just signed up in an as-yet-unspecified role to join Tom Hardy, Noomi Rapace, Gary Oldman, and Joel Kinnaman. The film is due out in 2014.
