Focus Features will release Miramax’s “The Debt” on Aug. 31 after the film lost Disney as its distributor in October. UPI will handle international distribution.Pic, starring Sam Worthington and Helen Mirren, is the second of a trio of shelved Miramax titles to secure a release date. Last week Miramax announced that it would partner with Tribeca Films to release “Last Night,” also starring Worthington along with Keira Knightley, in the spring. “Given Focus’ tradition of dramatic thrillers that unfold in exotic locations, ‘The Debt’ makes for a worthy addition to our 2011 release slate,” Focus CEO James Schamus said in a statement. The last of the three films, Guillermo del Toro’s “Don’t Be Afraid of the Dark,” has not yet locked down a domestic distributor; Pathe Intl. picked up international last month.” The Debt” centers around three Israeli secret agents and their decades-old hunt for a Nazi war criminal. Matthew Vaughn, Eitan Evan, Eduardo Rossoff and Kris Thykier produced.
