Alien (franchise)

Films in the series included Alien (TV: Last Christmas, Dreamland, et al.) and a sequel. (TV: Dreamland)

History
When the Enemy became one with the Life-spores, they travelled to Earth in 1967. In order to go further back, they inserted themselves into the "meta-flow" of popular culture, in an era imbued with "iconic energies". They gained the power they needed in order to travel back into the Old-times. (PROSE: The Annotated Autopsy of Agent A)

Fact or fiction?
Not uncommonly for Doctor Who, the events depicted in the Alien films are both established to be works of fiction and reality for the denizens of the DWU, in that the Xenomorphs exist in-universe, seemingly contradicting references to the films also existing in-universe. PROSE: The Annotated Autopsy of Agent A was a short story which tried to provide an explanation for this, positing that the life-spores were one identity of the Enemy, which inserted themselves into the meta-flow of Earth's popular culture, thus explaining that the films were based upon the life-spores. The story goes onto pass commentary of the further-evolving lore of the Alien franchise. The only downside is that the life-spores, while heavily implied to be Xenomorphs, aren't quite the same thing, and not just in name. For one, they reproduce via spores, not Facehuggers.

On the topic of Facehuggers, they have been confirmed to be part of the in-universe franchise in TV Last Christmas. Though, they were first mentioned in PROSE: The Left-Handed Hummingbird, which was ambiguous regarding their existence as reality or fiction.

Furthing the "mythos" that the events depicted in the Alien franchise are a reality in the DWU, an animated reconstruction of TV: The Power of the Daleks had a brief easter egg depicting the Weyland-Yutani Corporation's logo on a monitor.

Other matters
During series two of Doctor Who, the website whoisdoctorwho.co.uk was updated to be run by a "David R" - the character, who had information about him detailed in a mock-biographical way on the BBC Cheapserve website, mentioned that he was a fan of the Alien movies, but not.
