Jim Loach directed the story about a social worker who uncovered the British government's forced deportation of poor children to Australia and Canada — frequently without their parents' knowledge.
In many cases, the children were told that their parents had died.
Watson ("Breaking the Waves," "Hilary and Jackie") stars as Margaret Humphreys, the social worker. Weaving ("The Matrix") and David Wendham ("300," "Public Enemies," "Lord of the Rings") also star.
Rona Munro ("Ladybird Ladybird") wrote the script.
Camilla Bray, Iain Canning and Emile Sherman produced.
Cohen Media Group acquired the film from Icon Entertainment, which produced.
Cohen's first release, 2010's "Outside the Law," directed by Rachid Bouchareb, was nominated for the best foreign language Oscar.
