Will we ever get over this thing called civilization? That's what I wondered as I watched The Embrace of the Serpent, directed by Colombian filmmaker Ciro Guerra, a black-and-white film in several indigenous and European languages that has some of the qualities of a documentary. But this is a truer-than-history fiction, fabricated out of the travel diaries of two botanists, Theodor Koch-Grunberg (Jan Bijvoet) and Richard Evan Schultes (Brionne Davis), both of whom traveled in the Amazon region, the former in 1909 and the latter in 1940. The challenging and sometimes horrifying experiences of the two scientists are linked together by the character Karamakate who serves as guide to both and a challenge to each. (Nilbio Torres plays the young Karamakate and Antonio Bolívar the old Karamakate.) Both botanists are looking for yakruna, a rare, sacred, and hallucinogenic plant, and their search takes them into the jungles inhabited by peoples menaced by the encroaching modern world.
