There are those who would compare The Treasure of the Amazon to Raiders of the Lost Ark (1981). They would be wrong. OK, This could have been an excellent movie, but it is not. The cast is great and at times actually demonstrates it, but the plot is so thin and ridiculous that it is extremely difficult to get into it at all.
Stuart Whitman stars as your typical aging adventurer who leads a group of misfits into the Amazon to find lost WW2 treasure. Most of the group is killed in various horrible and ridiculous ways. The only way I would recommend this film is if you are interested in seeing some top notch actors doing their best to make something of nothing.
The cast includes Whitman, star of such wonderful films as Rio Conchos and The Comancheros as the bull headed leader. Bradford Dillman, who starred opposite Robert Redford in The Way We Were, makes an appearance. Donald Pleasence, star of many classic films such as The Great Escape and The Eagle Has Landed, plays an evil Nazi. Rounding out the cast are John Ireland(Gunfight at the OK Corral 1957),Pedro Armendariez Jr.(License To kill 1989)and none other than Harold(Odd Job)Sakata.
