There’s big trouble in paradise in this true-life story rife with melodrama, exotic lifestyles, sexual intrigue and suspicious deaths. This inescapably fascinating documentary about a handful of eccentric Europeans who couldn’t get along when they settled on one of the tiny uninhabited islands in the Pacific west of South America in the early 1930s combines contemporary material with fantastic film footage taken at the time and excellent dramatic readings by a fine international cast, including Cate Blanchett. The Galapagos are usually perceived as pristine nature untrammeled by human influence. But some of the nearly 20 islands are very much settled by human beings. Directed by Dayna Goldfine and Dan Geller.
