Audio problem: When Julie walks into Nathan Bates' office and says 'I've got a question for you' her lips do not match what is heard. (00:33:55)
Deliberate mistake: Several shots have been taken from Series 1, including the group of guards firing in the hangar bay, and various shots of the shuttles during the chase.
Continuity mistake: When Kyle and Sarah arrive to help Mike and Ham, they drive through a group of Visitor guards, who all dive onto the embankment out of the way. But two seconds later, two of the guards are back on the dirt track. (00:35:40)
Revealing mistake: Extremely obvious stunt double for Kyle Bates when he escapes from the clutches of Mr Chiang and jumps off the roof. The stunt double looks absolutely nothing like the actor, and his face is very visible. (00:39:00)
The Sanction - S2-E5
Revealing mistake: When Klaus skids and falls off his motorbike it is obviously a stuntman as his body is much stouter than the actor's. (00:17:25)
The Sanction - S2-E5
Visible crew/equipment: The boom mike appears briefly in the top left of the screen when Julie tells Mike to wait after he walks out of the meeting room. (00:07:05)
Continuity mistake: When Mike is about to kiss Diana, he puts his thumb on her chin. Then in the next shot his thumb is away from her chin. (00:28:20)
Visible crew/equipment: When Sean enters Mike's bedroom after the capture and says 'dad, you're awake', the boom mike is reflected briefly in the wall mirror. (00:18:40)
Deliberate mistake: The shot of the mothership landing bay and the arrival of Charles' ship is stock footage that has been used several times before. There is also a continuity error here - the view from the landing bay shows darkness outside, but the next shot shows broad daylight. (00:06:20)
Continuity mistake: When Elizabeth is pricked by the rose, there is a closeup of her bleeding finger. Before and after this shot Kyle is holding her hand, but not in the closeup. (00:03:25)
Audio problem: Just before Mike and Ham start shooting up the bridge, Jacob is seen being tortured, but his mouth is not moving with the sounds he is supposed to be making. (00:24:40)
Continuity mistake: When Kyle is with Donovan in the warehouse shooting at Philip, you always hear a bang coming out of the machine gun but sometimes a fire blast is not seen.
Revealing mistake: The two Elizabeths are both played by the same actress, except in the shots where both are seen together. Continuity mistakes in the second Elizabeth's death scene reveal this, such as the second Elizabeth's head position changing, and the first Elizabeth's jacket being open/closed between shots. (00:42:30)
Continuity mistake: When Diana is about to eat the white mouse, Donovan puts the tray of mice down on the bed, then in the following shot he puts it down again. (00:28:10)
Continuity mistake: When Ham Tyler is fixing the van in the garage, there is sunlight shining on him when the camera is facing out onto the street, but there is only normal daylight when the camera is facing inside the garage. (00:24:25)
Continuity mistake: When Mike pulls the necklace off the fake Julie, Julie's head is lying at a slightly different angle than when she changes into Lydia. (00:39:20)
Continuity mistake: Mike Donovan (riding a horse) is chased by a Visitor shuttle. It is obvious that there were recycled some shots from "The Final Battle" (Ep. 1). In "The Champion", Donovan does not have a laser pistol. However, there are some shots in which he has that pistol: obviously, those shots are taken from TFB.
Visible crew/equipment: When Julie says 'We're gonna stand and fight' near the end of the episode, a boom mike briefly creeps into view at the top of the screen. (00:42:15)
Revealing mistake: When the two wildcats throw hand grenades at the Visitors, the grenades are obviously fake because the explosions do not occur at the same place as where the grenades land. The detonations have obviously been located in a safe place away from the actors. (00:11:50)
