The natural-history documentaries produced by BBC Earth are widely regarded as the best in class, but its crowning achievement may be the latest, Enchanted Kingdom 3-D. The film places viewers deep within the wilderness of Africa, using state-of-the-art 4K 3-D cameras. This new dimension of BBC Earth's storytelling is further enhanced with high-definition time-lapse photography and micro and macro 3-D lenses to create a feeling of unparalleled presence. The film examines not only the critters that populate Africa's densest jungles, but takes audiences on a journey that reaches from the bottom of the continent's secretive seas to the tip top of its ice-capped mountains and lava-laced volcanoes. Enchanted Kingdom screens at 7 p.m. Monday and Tuesday (August 10 and 11) at Ronnies 20 Cine with IMAX (5320 South Lindbergh Boulevard; www.fathomevents.com). Tickets are $15.
