Director Gavin Hood gives the proceedings a rousing electricity, and he’s aided by a cast which leans into the story’s urgency and continued relevance.

A model of professionalism and energy, Official Secrets moves along at a brisk clip. It’s paced like a police procedural, but it focuses not on an investigator but rather a moral exemplar who takes a principled stand in defiance of the price that has to be paid.

Hood (Eye in the Sky), his co-screenwriters Sara and Gregory Bernstein and a seasoned ensemble of Brit stage and screen pros deliver a straightforward, solidly old-fashioned slice of real-life espionage, journalistic and legal intrigue that gets the job done in engrossing, clear-eyed fashion even if it lacks much in the way of stylistic verve.

Gavin Hood wrings suspense out of the parsing of the nuances of evidence and the tapping of mysterious contacts.

Official Secrets, despite its blasé title, despite the fact that this “true” story isn’t on a LeCarre level, in spite of its paucity of dramatic outbursts, is still a most engrossing history reminder.
