Critical
The Monthly Film Bulletin wrote: "This is an unusual production, but a monotonous series of flashbacks break the even development of the plot and it is difficult at times to keep track of the characters around whom the story is built. The result is that interest is lost and the film becomes boring. It is a pity, also, that so little use has been made of the South American river scenery. Bibi Ferreira gives character and charm to the role of Teresa and Sabu arouses sympathy for the bewildered boy Manoel." [7]
Kine Weekly wrote: "Drab romantic melodrama, meandering alongside the mighty Amazon ... The picture unfolds in a series of sordid flashbacks and retrospective presentation makes its involved, scenically overloaded tale all the more difficult to follow. For a time its finely photographed vistas and panoramas thrill, but after that all attempts to wade through its grisly detail and interpret its message become an unutterable bore. It's entirely lacking in feminine appeal and the rudiments of popular entertainment. It's a case of the nuts going to Brazil." [8]
The Radio Times described the film as "A curio," and concluded, "Despite a good cast and the Brazilian locations, the results are both confusing and disappointing." [9]
TV Guide wrote: "A confusing, mediocre film shot in Brazil, with little to recommend it to audiences elsewhere." [10]
Britmovie wrote, "Sabu is well suited for the role with his Indian good looks. He executes a credible performance... Bibi Ferreira is stunningly beautiful as his love interest... Esmond Knight, Orlando Martins, Robert Douglas, and Torin Thatcher all turn in solid performances... Even though parts of the story remain weak, the scenery definitely makes up for it. Christopher Challis is the cinematographer and he successfully portrays the life of the natives in the lush subtropical forests in Brazil." [11]
