When Waris Hussein first enters Verity's office, he is holding a script in his right hand. During reverse shots, he continues holding the script in his right hand, with both arms down by his side, but in forward-facing shots, the script is in his left hand and he is gesturing in front of him with his right.

During the recording of the pilot it's shown that the lights go out and the sprinklers turn on due to the heat, neither of these incidents occurred during the recording, and although Warris Hussein did recall that if Studio D at Lime-grove got too hot the sprinklers would turn on, this never occurred when Doctor who was filming.

This shows Melvyn Pinfield being involved in the casting of Patrick Troughton. But Pinfield had left in the middle of the Hartnell years because of illness forcing him into retirement.

In the opening scene where William Hartnell is driving across Barnes Common, he stops at real police call box. When the constable is leaving the box, he opens the door inwards, as with the TARDIS. Genuine police box doors, due to the lack of space inside,open outwards. Additionally, real police boxes were taller and wider than shown, and were made of concrete, not wood.

Claudia Grant playing Carol Ann Ford/Susan Foreman explains that TARDIS stands for Time and Relative Dimensions in Space whereas in both the un-aired pilot and pilot of an Unearthly Child she says Time and Relative Dimension in Space - no 's' at the end of Dimension.

William Hartnells discovery of the Assassination of JFK is presented as happening on the same day as the first broadcast, in reality he discovered the news during the recording of the Second Episode of The Daleks the day before.

During the rehearsal scene for the first episode, there is a shot of Verity Lambert, leaning on a monitor that is showing a test card. In the top left corner of the testcard you can see the "play" icon of a DVD-Player OSD, in the top right corner the track information "44/44".

Matt Smith's Eleventh Doctor was green-screened into the scene with his cameo. In the second shot of him standing across from William Hartnell, his left shoulder is in front of the TARDIS time rotor, a position impossible given where he is standing.

In a scene set in 1963 and BBC Television Centre, Mervyn takes Verity into the News Studio however BBC News didn't move to Television Centre until 1969.

Although the opening scene takes place in 1966, a "Yearometer" in the TARDIS winds back to 1963 to indicate that the majority of the film take place in the earlier year. However in the establishing scenes at BBC Television Centre, a Triumph Herald with a C suffix on the registration plate (denoting that it was first registered in 1965) is seen.

In the establishing external shots of William Hartnell's house, the car parked outside is a D registration which was 1966 even though the scenes pass through 1963 to 1965.

Hartnell's young granddaughter Judith does not age, although she has scenes set three years apart, in 1963 and 1966.
