Tale of the Mummy

In 1948 Egypt, an archeological dig led by Richard Turkel (Christopher Lee) reaches a tomb (of Talos), which is apparently cursed. The hieroglyphics at the entrance warn that all should avoid the place as it has been abandoned by all that is holy. Despite this, they proceed to open the chamber's door only to be blasted with a cloud of dust, which causes them to crumble apart as though they are made of fragile stone. Richard manages to blow the tomb shut, killing himself in the process.
