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)
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 Mike radios Elias he identifies himself as 'wilderness' calling 'Shiloh'. When Elias acknowledges, he also identifies himself as 'wilderness' instead of 'Shiloh'. (00:33:20)
Revealing mistake: When Diana blasts Lydia's shuttle, there is an explosion but the craft is still visible and intact for a brief second. (00:45:20)
Visible crew/equipment: In all of the shots of Elizabeth and Jacob facing down the highway, there is a black piece of equipment protruding from the left side of the screen. (00:42:20)
Continuity mistake: The Visitor craft that Mike and Ham capture is not the same type that is seen later entering the hangar. The first one is a small shuttle, the second is a transport, distinguishable by the windows on the side. (00:20:10)
