I watched this on a Spanish language channel in Orlando, FL back in the early '90s. They did something right with "Ladrones du Tomba" since I watched the entire film and did not speak very much Spanish at the time. It has all the ingredients of an entertaining slasher: cool, low budget Indiana Jones angle with the grave robbers, foolish, reckless teenage characters, a zombie killer with a battle axe and a beautiful "last girl" that has lungs to give even Jamie Lee Curtis a run for her money. It doesn't have a big Hollywood budget and a lot of the night time scenes were dark and murky but it did not skimp on the blood and gore. The latter looks fake at times but this was not unusual for this time period for special effects. LDT is a must for B-horror movie aficionados if you are able to find it.
