Doctor Who: Pyramids of Mars (1975)

In a Victorian Gothic mansion, strange things are afoot. The master of the house, away in Egypt, has been replaced by a sinister Egyptian. Cloth-wrapped Mummies roam the grounds, killing people. Beneath a pyramid, the last of the Osirans — Sutekh the Destroyer — waits to be freed, to at long last bring his gift of death to all who live.
