Director Joshua Zeman (with Executive Producers Leonardo DiCaprio and Adrian Grenier) brings along on a quest that’s both scientific and spiritual: connecting with the “52 Hertz Whale,” which may have spent its entire life in solitude, calling out at a frequency that is different from any other whale. Cinematic and engrossing, this journey teaches us about the ocean, and ourselves. (U.S., 2021, 96m). Opens July 9.
