The plane crashes in the jungle and old man archaeologist kicks the bucket right away.
They leave on foot and while crossing a river the photographer gets his leg eaten up by piranhas.
This movie has most of the elements. Plenty of nudity including bush, some gore and lots of action and adventure. What it lacks is the truly sadistic shit you come to expect from a Italian cannibal flick. Thankfully it seemed like no animals were killed in the making of this film which is actually quite a surprise!! Check this out if you are a completist (it's free) but if you haven't seen the original def watch that first.
