Children of Earth: Day One - S3-E1
Revealing mistake: When the children are possessed by the 456, they're supposed to be frozen and stare blankly ahead. But during the second possession, as the camera is panning across a school playground, a boy on the far right is looking directly at it. As it moves closer to him, he swivels his eyes back to where they're supposed to be. (00:16:30)
Captain Jack Harkness: Captain Jack Harkness, note the stripes.
Captain John Hart: Captain John Hart, note the sarcasm.
Captain Jack Harkness: Hey, I worked my way up through the ranks.
Captain John Hart: I bet the ranks were very grateful.
Trivia: Torchwood is an anagram for Doctor Who, the show of which this series is a spin-off.
