Alien (film)

Alien was a science fiction movie.

When John Jefferson mentioned the ducts used by maintenance robots that ran under Sanctuary Base 6, Rose Tyler assumed that they were ventilation shafts, to which Jefferson replies "I appreciate the reference". A chase through ventilation shafts was featured in Alien, and Jefferson's actor, Danny Webb, was in the film's second sequel, Alien 3. (DW: The Satan Pit)

Toshiko Sato compared the body of a dead soldier with his heart ripped out to scenes and characters from the movie. (TW: Greeks Bearing Gifts)

The Tenth Doctor referenced Alien and its sequels whist imprisoned within Area 51. The Viperox Queen and her eggs bore similarities to that of the Alien Queen and her eggs, as seen in the film's sequel, Aliens. (DW: Dreamland)

Jason Kane compared the reproductive cycle of the Charrl to the Aliens in the film. (BFBS: Birthright)

Izzy Sinclair compared being chased by the Daleks and their Contagium to being "an extra in an aliens film". The Doctor wryly agreed. (DWM: Fire and Brimstone)
