Oasis of the Zombies

This is an early 80s film about an oasis in the dessert where there is supposedly millions of dollars buried… and subsequently protected by zombies. An old army guy was killed searching for the treasure and his son and his gang of friends goes searching for it. I’m amazed at the number of times people just show up and start digging at this huge valley-wide oasis (and they always have someone digging in the soft sand with a huge pick-axe for mining – weird). I’m also amazed that in the 80s they didn’t utilize the film technology to shoot scenes in the dark instead of shooting in bright daylight (casting shadows and illuminating various objects) and using some sort of dimmer or filter to make it appear dark outside. The zombies appear to be old Nazis, but the army colonel who was in charge of them was an American (and his son is British). This movie kind of fizzles at the end, and it doesn’t help that it’s pretty stupid through the rest of it.
