Continuity mistake: In the opening scene, Gwen has a long, loose strand of hair hanging over her left temple - but every time the camera angle changes, it disappears. (00:01:00)
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)
Revealing mistake: From the first "front on" view of Gwen and Owen in the arcade as they are running to catch the alien device, you can see behind Gwen to the right that Owen is being played by a stunt double.
Cyberwoman - S1-E4
Character mistake: In this episode Jack tells Gwen that he does not sleep, yet the next episode, Small Worlds, begins with Jack asleep and dreaming of the day his comrades died on a train, with rose petals in their mouths.
Countrycide - S1-E6
Continuity mistake: In the pre credits sequence, when the lady gets out of her car the antagonist slashes her rear tyre however after the antagonist is attacking her inside the car we see a rear shot of the vehicle, and the tyre is fully inflated.
Continuity mistake: While she's talking to Mary in the flat, Toshiko's hair keeps changing between shots, going from combed evenly to split apart with one section hanging in the middle of her forehead and the rest brushed back. (00:31:30)
They Keep Killing Suzie - S1-E8
Visible crew/equipment: When Owen responds to Susie talking through the computer monitor and says "you frighten the s**t out of me" a boom mic drops into shot above his head.
Out Of Time - S1-E10
Continuity mistake: John is about to eat liver and potato with Emma before she storms out saying, "I don't like liver". While they are talking, the potato is facing Emma and Gwen. After Emma leaves, the liver faces Gwen and the spot where Emma was.
Factual error: Between getting disconnected by the bad guy and calling Ianto, Jack gets a dial tone on the dead man's cell phone. Cell phones don't generate dial tones. (00:11:10)
Captain Jack Harkness - S1-E12
Factual error: When Gwen finds Toshiko's hidden message from 1941, she realizes that it was written in blood, and her flashlight reveals the bright red letters on the now-yellowed piece of paper. But after 60+ years, the iron in the blood would oxidize. The writing on the note should be rust-brown, not red. (00:33:40)
Captain Jack Harkness - S1-E12
Factual error: "Captain" Jack Harkness actually wears the rank insignia of a group captain, equivalent to an army colonel and never abbreviated to "captain". In fact, the RAF does not have a rank of captain (the equivalent rank is flight lieutenant). Neither does it have the position of "squadron captain", as he is described - a squadron commander in World War II usually held the rank of squadron leader (equivalent to an army major).
Suggested correction: "Captain" Jack Harkness actually wears the rank insignia of a group captain, equivalent to an army Brigadier. The equivalent rank of Captain in the RAF is Flying Officer.
Nope. Group Captain = Colonel (Air Commodore = Brigadier). Flight Lieutenant = Captain (Flying Officer = Lieutenant).
Group Captain in the RAF does in fact equate to Captain in the Royal Navy. The Army equivalent being, as stated, Colonel.
End Of Days - S1-E13
Visible crew/equipment: After Lisa appears to Ianto in the holding area, she disappears, when the camera changes angles you can still see her standing in the corner of the room on the right side of the screen. (00:12:50)
Continuity mistake: During the interrogation sequence in the Torchwood hub Gwen's position moves in relation to the grate from the centre to the sides between shots.
Continuity mistake: In the scene on the pier with Toshiko and Tommy, the soldier from WWI, Toshiko is holding her hand bag but drops it when he picks her up. Immediately, the next shot she is holding it again.
Factual error: Owen resuscitates Tommy using a defibrillator. The heart monitor shows a flat line, indicating Tommy's heart is not beating. A defibrillator has no effect in this situation. This is a widespread error in many films and TV shows.
Continuity mistake: Gwen views a transparency of two Torchwood members from 1918. The words "Torchwood" can be seen behind them. When Ianto takes the transparency and holds it up, the slide is different: it contains five people and the word "Torchwood" is above their heads.
Continuity mistake: While he's in the van with Jack, Rhys's seat belt shoulder strap vanishes and reappears multiple times as the shots change. (00:27:40)
Continuity mistake: When the man is being terrorised by the weevil, in close up shots, the weevil is about 6 inches from the man's face. However in the long shots, it is about 3ft away from him. (00:34:35)
Factual error: Martha picks up a bone saw to start the autopsy on Owen. An autopsy should start with a Y incision from just below the arm pits to the sternum and then down the stomach to the pubic region - using a scalpel, not a bone saw.
Continuity mistake: When Maggie walks away from the car accident, the blood smears on her white gown change repeatedly from shot to shot. (00:16:30)
