Six smart, tough guys, tightly framed and talking to the camera: Israeli filmmaker Dror Moreh's compelling Oscar-nominated doc The Gatekeepers gives the voice of experience a human face.

With such incendiary opinion on offer, it might have been a temptation for Moreh to lay out these testimonies end to end... What makes the film so satisfying, though, is the appreciable craft with which the material is organized and presented.

Moreh's interviewees span generations, from elder statesman Avraham Shalom (mastermind of the 1960 Adolf Eichmann grab) to most recent spook-in-chief Yuval Diskin. Each displays a disarming mix of even-voiced candor and respect for talk-it-out diplomacy.

Divided into seven segments, 'The Gatekeepers' does not stick to a chronological telling of history but instead hopscotches around to establish a throughline of morality, which is what director Dror Moreh seems to be most interested in.
