“Into the Inferno”: As the title promises, Werner Herzog’s latest globe-trotting adventure plunges us into the bowels of the Earth. But there’s more at play than surreal images of lava spewing: The versatile filmmaker connects how volcanoes have shaped history, cultures and our environment. Herzog fears nothing but boredom, and he and volcanologist Clive Oppenheimer, author of 2011’s “Eruptions That Shook the World,” take us on a wild tour of volcano hot spots, where we hear from inhabitants living in fear of nature’s unsparing force and meet the curious researchers in locales that include Indonesia, New Zealand and Iceland. Watch for an appearance by UC-Berkeley’s palaeoanthropologist Tim White in East Africa. (Netflix) 1:44

“Sky Ladder: The Art of Cai GuoQiang”: The Chinese-born artist generated many oohs and ahhs worldwide with his controversial fireworks ceremonies at the 2008 Beijing Olympics.

Macdonald dedicates most time to showing Cai’s grand spectacles, including a massive operatic fireworks display that mirrors the dawn of creation, and then on to his fiery 1,650foot ladder.

“Blue Jay”: When two high school sweethearts (Mark Duplass and Sarah Paulson) reconnect 20 years later, the attraction’s still there, as are the emotional wounds. Shot in black and white and staged like a two-character theater piece, this talky adult drama works because the talented twosome understand the nuances of Duplass’ painfully realistic script.
