NEW YORK (AP) — There’s a new nature documentary series that promises to show viewers incredible animal behavior in vibrant clarity. Heard that all before? Well, this one is on steroids. “Super/Natural,” a six-part series from National Geographic on Disney+, has tapped “Avatar” creator James Cameron as executive producer, and he’s added special effects on top of leading-edge filmmaking technology. The effects sometimes morph the animals into something like stars in a Marvel movie, with their bellows distorting the air, lumbering attacks that cause shock waves in sand or pheromones from an insect rendered as bursting noxious clouds. Even trees light up when sugars move through their roots.
