Guy Lodge Film Critic Doug and Kris Tompkins’ dream sounded like a fanciful one. Seduced by a region of ravishing South American wilderness in which they found particular sanctuary, and wishing to protect it from any insensitive or unseemly development, they landed on a solution both simple and absurd-sounding: Why not simply buy as much of it as possible? Backed by the fortune they’d collectively amassed from the clothing industry — Doug as the founder of Esprit and The North Face, Kris as the former CEO of Patagonia — the couple successfully parlayed business tycoon status into an unprecedented scale of eco-activism: As one talking head notes in “Wild Life,” Elizabeth Chai Vasarhelyi and Jimmy Chin’s soaring documentary tribute to the Tompkins’ romance and shared conservationist mission, they “could do anything, and chose to do anything.”
