Children of Earth: Day One - S3-E1
Character mistake: Lois says that Colonel Aduya's uniform "isn't British Army". In fact, it is entirely (and accurately) British Army with the exception of the small UNIT badge over the pocket.
Torchwood (2006)
1 character mistake in Children of Earth: Day One
Starring: John Barrowman, Eve Myles, Gareth David-Lloyd, Kai Owen
Continuity mistake: When she sees the little boy's ghost, Gwen's hair alternates repeatedly between neatly-combed and windblown/messy, depending on the shot. (00:03:30)
Captain Jack Harkness: Under normal circumstances, an exuberant Roman soldier would be my idea of a perfect morning.
Trivia: Torchwood is an anagram for Doctor Who, the show of which this series is a spin-off.
Question: How did Jack get the Doctor's severed hand?
Answer: He might have requisitioned or stolen it from Torchwood London, or he might have been ready down below once it'd been severed, searching for "the right Doctor" and not knowing that the newly-regenerated Doctor was the one he was looking for.
