The life story of the late Oliver Sacks, the neurologist and author who revived the medical case history with such bestsellers as “The Man Who Mistook His Wife for a Hat” and “Awakenings” — the latter inspiring an Oscar-nominated film by the same name — is told in the moving documentary “Oliver Sacks: His Own Life.” True to its title, the film uses Sacks himself to tell most of the tale, from his somewhat wild youth to his coming out as gay in 2015, mere months before his death. Standard-issue talking-head interviews are interspersed with voice-over by Sacks reading from his 2015 memoir “On the Move,” shortly before his death. That title is also telling: Sacks was a restless intellect, passionately curious not just about the quirks of the mind — his brother Michael was schizophrenic — but about the power of storytelling. “His Own Life” is a compassionate, endlessly fascinating testament to that, as well as to the assertion, by one of Sacks’s friends, that the man’s placid acceptance of mortality offered a “master class in dying.” Unrated. Available at afisilver.afi.com and virtualavalon.org. Contains strong language and discussion of sexuality and drug use. 116 minutes.

It’s taken five years for “We Are Many” to get to American audiences, but somehow the timing seems right. Amir Amirani’s stirring documentary revisits the events of Feb. 15, 2003, when nearly 300 million people around the globe took to the streets to protest the U.S.-led invasion of Iraq. Beginning on Sept. 11, 2001, “We Are Many” reviews the spurious case that George W. Bush and British prime minister Tony Blair made for going to war, tracing a steadily building drumbeat created by official lies, a supine press and a cynical marketing campaign. When the global protests burst forth, it was a moment of power and clarity. Of course, it didn’t make a difference, as observers as wide-ranging as retired Col. Lawrence Wilkerson, author John le Carré and actor Mark Rylance correctly note. But “We Are Many” argues persuasively that the public engagement of 2003 had a direct effect on the Arab Spring several years later. What’s more, the lesson — that marches are good for the soul but that it takes sustained action and organization to effect real change — couldn’t be more germane at a time when most American citizens are grappling with a combination of impotent rage and hopeless despair. Unrated. Available at virtualavalon.org. Contains brief obscenity and disturbing wartime images. 110 minutes.
