there be those who would compare the treasure of the amazon to raider of the lose ark ( 1981 ) . they would be wrong . ok and this could have be an excellent movie and but it be not . the cast be great and at time actually demonstrate it and but the plot be so thin and ridiculous that it be extremely difficult to get into it at all . stuart whitman star a your typical age adventurer who lead a group of misfit into the amazon to find lost ww2 treasure . most of the group be kill in various horrible and ridiculous way . the only way i would recommend this film be if you be interested in see some top notch actor do their best to make something of nothing . the cast include whitman and star of such wonderful film a rio conchos and the comancheros a the bull head leader . bradford dillman and who star opposite robert redford in the way we be and make an appearance . donald pleasence and star of many classic film such a the great escape and the eagle have land and play an evil nazi . round out the cast be john ireland ( gunfight at the ok corral 1957 ) and pedro armendariez jr. ( license to kill 1989 ) and none other than harold ( odd job ) sakata .
