Visible crew/equipment: In the scene where Jarod is being thrown into the swimming pool by Zed, the gang leader, as a sort of initiation, there is a shot where Jarod is tied up in chains sitting in a chair at the bottom of the pool. Another character is set to throw in the key just to the next of Jarod and he is supposed to fall over and get it. In the shot just before he falls over, you can see a crewmen's arm holding a chain attached to the chair in order to help Jarod fall over.
Other mistake: At the start of chapter 12 in the episode "Kingdom Come," Frank returns home via taxi. In front of his house in Seattle, WA, there is a blonde woman walking a Rottweiler dog. This same blonde and Rottweiler can be seen walking by the crime scene in San Francisco in the "Gehenna" episode.
Plot hole: When Nicky goes into prison in Mexico to give a criminal a shot of insulin, two errors are seen. 1) The needle and syringe are far too big for an insulin shot, which takes a one ml syringe and a small sub-cutaneous needle. 2) When we first see the syringe, there is a small amount of insulin in it, but it grows the more times we see it, until a large syringe is two-thirds full - insulin is enough in a one ml syringe.kh1616
