Karski & the Lords of Humanity

Gathering vintage interviews from a couple of different documentaries, the film movingly observes a man who can be physically unsettled by things he saw several decades prior.

Karski & the Lords of Humanity is fascinating, but Mr. Lanzmann’s efforts tower over it.

In their abstraction, a number of striking animated sequences prove more effective in conveying these horrors than the talking-head segments that contextualize them.

Although it is often moving, the film is less satisfying than it could be.
