Shirley Eaton stars as Sumuru, the barbaric leader of an Amazon tribe, in Jesus Franco's uninspired adventure based on characters created by Sax Rohmer. Banker Ennio Rossini (Walter Rilla) hires a detective named Jeff Sutton (Richard Wyler) to travel from Barcelona to Brazil in search of his kidnapped daughter Ulla (Marta Reves). Sutton and a hotel manicurist (Maria Rohm) team up to save the girl from Sumuru's clutches but must deal with unexpected complications in the form of Sir Masius (George Sanders), a sadistic Great White Hunter out to steal Sumuru's gold. Sanders is wonderful (in one of his final roles before his suicide) but the numerous production problems (including a lawsuit by Rohmer's estate which led to Sumuru being renamed Sumitra in several prints) keep the film from being truly worthwhile. Typical of many European genre efforts of the 1960s, this was a Spanish-German-British-American co-production. All scenes involving the banker were cut from the American print, which also heavily trimmed the torture and sex, replacing some of the missing footage with stock Rio de Janeiro tourist scenes. Versions run 84 and 79 minutes. ~ Robert Firsching, Rovi
