Angry natives or a beautiful widow -- which poses the greater threat? Keith Brandon (Douglas Fairbanks Jr.) is an archeologist leading a team of researchers -- Richardson (Vincent Price), Loren (Alan Hale), Forrester (George Sanders), and Scott (John Howard) -- who are exploring the jungles of South America in search of Inca artifacts. The scientists discover they are not welcome when Richardson is felled by a poisoned dart, and a difficult situation is made all the more complicated when Stephanie (Joan Bennett), Richardson's wife, appears unannounced to pay her husband a visit. Stephanie must join Brandon's party as they make their way through the wilderness, with angry and armed natives surrounding them on all sides, and in the midst of the tension and danger, both Brandon and Forrester discover they're attracted to to Stephanie, leading to a dangerous rivalry among the crew. Green Hell would turn out to be the last feature film completed by the noted and idiosyncratic horror director James Whale; while he was credited with another film, They Dare Not Love, Whale in fact backed out of the project before shooting was finished.
