"Human, All Too Human" is a three-hour BBC series from 1999, about the lives and work of Friedrich Nietzsche, Martin Heidegger, and Jean-Paul Sartre. The filmmakers focus heavily on politics and historical context -- the Heidegger hour, for example, focuses almost exclusively on his troubling relationship with Nazism.
The most engaging chapter is "Jean-Paul Sartre: The Road to Freedom," in part because the filmmakers had so much archival footage and interview material (Check out a still lovely Simone de Bouvoir at minute 9:00, giggling that Sartre was the ugliest, dirtiest, most unshaven student at the Sorbonne).
