A Visit to the Cinema (short story)

 was a Brief Encounter short story published in Doctor Who Magazine 190. It depicted Dr. Who and the Daleks and Daleks' Invasion Earth 2150 A.D. as fictional elements within the Doctor Who universe.

Summary
The Third Doctor has a bit of free time on his hands, which is rare for him, and so goes to the cinema to watch a double-bill of a particular couple of movies starring Peter Cushing.

Characters

 * Third Doctor

Worldbuilding

 * The Doctor refers to Peter Cushing as "that splendid chap Van Helsing".

Parody or straight?
While the films are never specified by name, the story suggests that the events of the 1960s Dalek films are fictional parts of the DWU: the Doctor is entertained by a memorable moment for Roy Castle's character in Dr. Who and the Daleks. Later, two elderly ladies sitting next to the Doctor — who have disapproved of his outbursts of amusement — exclaim that they wish the Doctor would develop the manners of "that lovely Mr Cushing". Likewise, The Doctor compares the "bizarre eye make-up" worn in the film to that employed by Jo Grant, making light of the make-up used on the Thals in Dr. Who and the Daleks to make them appear more alien than their televised counterparts.

However, the reader is also given scope to imagine it's parody when the Doctor says, "How wonderful to have seen that particular planet in colour at last." The Doctor can't be referring to Skaro here, because obviously he would have seen it in colour, even if TV viewers did not. Yet, if it's not Skaro he's talking about, then he's not watching Dr. Who and the Daleks. Thus, this can be read as a comment, which takes the piece closer to parody. This is all only as far as the authorial intent at the time could be considered; however, long after the short story's release, Steven Moffat's novelisation The Day of the Doctor revealed that the Doctor's first and second incarnations were colour blind, giving a perfectly good in-universe reason for the Doctor not to have seen Skaro in colour by the early days of his third incarnation. The Day of the Doctor also suggests that the films exist as fiction within the Doctor Who universe, revealing that the Eleventh Doctor was such a fan of the films that he went back in time to make friends with Peter Cushing, even lending him the waistcoat he wore in Daleks: Invasion Earth 2150 A.D.

Continuity

 * The UNIT Black Archive contained VHS cassette copies of Dr. Who and the Daleks and Daleks: Invasion Earth. During the creation of the peace treaty between the humans and Zygons, the Tenth Doctor and the Eleventh Doctor watched the films and then pitched a third to Peter Cushing on the phone. (PROSE: The Day of the Doctor)
 * By another account, Dr. Who and his eight-year-old granddaughter Suzy were creations of the real Doctor to distract the Five O'Clock Shadow. (PROSE: The Five O'Clock Shadow)
 * The Doctor could only see in monochrome until his third incarnation. (PROSE: The Day of the Doctor)
