The cinematography is quite good, only occasionally reminding the viewer he's wondered onto the Jess Franco territory via some blurry shots and slightly jerky pans. There's also a number of well-executed tracking shots - a rare treat from Tio Jess! The acting is suprisingly on a very decent level, too.
The stubbly Thomas Hunter sort of looks like a cross between James Franciscus and George Hilton and does a good job with his bland do-right protagonist.
So, the cast is quite good, technical credits are competent - why is this film so obscure then?
The script is really slow and full of jungle cliches: you get snakes, hostile natives, someone cutting through the bushes with an obligatory machete...
The film does drags on in a couple of places but pics up nicely towards the end with some semi-lively action.
Howard Vernon's moustache! It's as bad as the one Antonio Mayans was forced to wear in Sadomania.
The Oracle DVD has a pretty funny animated menu screen which fetures a more spectacular plane crash then the main feature!
