“The Engineer” (** out of four) was a pretty mild action espionage thriller based on true events about a former C.I.A. agent (Emile Hirsch) who is called back into action for one of the biggest manhunts in history to find criminal mastermind Yahya Ayyash (Adam Haloon) who oversaw multiple suicide bombings and mass destruction in Israel in the mid-90’s. Initially strong and engrossing with some sharp dialogue and topical plot details but film gradually sputters and loses its momentum and focus more as it goes along. Robert Davi has a small but key role as an Israeli businessman; him and Hirsch also starred in this week’s “Inside Man” together.
