Visible crew/equipment: At the funeral of Tsi and Keene, when Jeremy is talking to Jack and the TV camera, we see the lighting rig reflected in Angela's sunglasses. There is also someone standing in front of the rig. (02:44:05)
Visible crew/equipment: When Jeremy calls Jack, Jeremy is in an office alone. At one point there is a shadow in the background of a person moving around. Since nobody else is in the scene, it must be a crew member. (01:19:20)
Other mistake: When the team is in the grocery store, they rewind the security videotape (they play it backwards). They stop it at the last activity, when a man comes in and chainsaws his own head off. The body (and head) have gone blue/purple, and since everyone else died the previous night, we can assume that he cut his head off around 12 hours ago. At high speed reverse play, the time they spent rewinding would be only around 10 or 15 minutes of recorded time. (00:32:50)
Dr. Jeremy Stone: So, you're saying they survived Andromeda because they had the same level of stomach acid? That's brilliant.
