Pyramids of Mars is the third serial of the 13th season of the British science fiction television series Doctor Who. Written by Robert Holmes and Lewis Greifer under the pseudonym of "Stephen Harris" and directed by Paddy Russell, the serial was first broadcast in four weekly parts on BBC1 from 25 October to 15 November 1975. The serial is set in England and Egypt and on Mars in 1911. In the serial, the burial chamber of the alien Osiran Sutekh (Gabriel Woolf), the inspiration for the Egyptian god Set, is unearthed by the archaeology professor Marcus Scarman (Bernard Archard). Alive but immobilised, Sutekh seeks his freedom by using Professor Scarman as his servant to destroy the jewel in a pyramid on Mars which is keeping him prisoner. Influenced by the gothic horror genre and films such as The Mummy, the serial was met with widespread critical acclaim, being praised for its atmosphere and production. Plot In 1911 Egypt, archaeology professor Marcus Scarman excavates a pyramid and finds the door to the burial chamber is inscribed with the Eye of Horus. His Egyptian assistants flee in fear as he enters the chamber alone and is hit by a beam of green light. The Fourth Doctor, intending to land in UNIT's base, ends up in the sealed wing of an English estate after the TARDIS was forced out of its flight path and Sarah Jane Smith sees an apparition of a Typhonian Animal in the console room. The two are found by the butler, who reveals they are in the Scarman estate, an old priory, which has been taken over by a mysterious Egyptian named Ibrahim Namin claiming to represent Scarman. Scarman's friend Dr Warlock has also arrived at the priory to demand an explanation from Namin on Scarman's whereabouts. When Namin threatens Warlock with a revolver, the Doctor and Sarah barely manage to prevent his murder, although Warlock is severely wounded. The three escape the estate, with Namin and a robot dressed like an Egyptian mummy in pursuit. The trio reach a hunting lodge used by Scarman's brother Laurence, whose marconiscope intercepted a signal from Mars. The Doctor decodes the signal as "Beware Sutekh", explaining to Sarah Jane that Sutekh is the last of a powerful alien race called the Osirans, his imprisonment by his brother Horus being the inspiration for ancient Egyptian mythology. Namin and the mummies greet the arrival,
