Continuity mistake: When the three bride Autons attack Jackie, and they open their hands one at a time, it is clear that when the second Auton opens its hand, all three are already open. After it cuts to Rose, and back to Jackie again, the third one opens (even though we just saw it already open).
Continuity mistake: Just after the Doctor makes his appearance and Lynda tells him he's "in the house", she appears to continue talking to him but we never hear what she says; instead we see and hear the other two "housemates" complaining about the Doctor's sudden appearance.

Continuity mistake: Near the beginning of the episode, the Doctor and Jack destroy a Dalek who is inside the Tardis and you later see it when the Doctor, Rose and Jack come back into the Tardis after talking with the Emperor Dalek. Yet later when the Doctor is sending Rose home, there is no destroyed Dalek.
