Factual error: Lincoln Burrows is scheduled to die on May 11th, 2006. When Veronica learns of the priest's death, we see a wall planner on the wall with May 11th circled in red marker. The day on the wall planner is Wednesday. However, May 11th, 2006 was a Thursday. (00:32:00)
Riots, Drills and the Devil: Part 2 - S1-E7
Continuity mistake: When T-Bag is talking about acne, the way he holds the picture of Bob's daughter changes between shots. Note his index finger. (00:29:10)
And Then There Were 7 - S1-E11
Continuity mistake: The severity of Quinn's wound changes throughout the episode. (00:04:00 - 00:39:30)
And Then There Were 7 - S1-E11
Continuity mistake: When Michael goes through the wall for the first time, he lifts the grate and his hand is in the middle of the grate. When the shot changes, his hand is now at the edge of the grate he is moving. (00:11:10)
Continuity mistake: When Patterson brings the tray to Linc at the start, the position of the milk on the tray changes between shots. Note the corner of the tray. (00:09:40)
The Old Head - S1-E8
Continuity mistake: Michael hands out sledgehammers at the end and passes one to Abruzzi with the head facing down. Abruzzi then passes this one to Lincoln but the head is now facing up. (00:39:00)
The Old Head - S1-E8
Continuity mistake: Bellick visits Westmoreland in his cell and puts his cigs in his pocket as he walks into the cell. When he sits down, he puts the packet away again. (00:25:40)
Riots, Drills and the Devil: Part 2 - S1-E7
Continuity mistake: When we see a military truck driving onto the grass at the start, it is by a white patrol car. When the shot changes to a ground level shot, the patrol car has gone. (00:03:10)
Riots, Drills and the Devil: Part 1 - S1-E6
Continuity mistake: We see Sarah banging on the window of the sick bay at the end. When she does this, she is banging with one hand and resting her other hand on the glass. The hand that is on the glass changes position during instant cuts. (00:41:00)
English, Fitz or Percy - S1-E5
Continuity mistake: When Nick and Veronica are trying to get the original tape, the folder and clipboard on the desk keep moving and changing positions between shots. Note the gap between them. (00:29:50)
And Then There Were 7 - S1-E11
Continuity mistake: When Quinn falls in the well, he falls through and subsequently destroys the well cover. At the end of the episode when the Secret Service boys show up, an undamaged cover is lying next to the well, which Kellerman uses to cover it up. (00:29:30 - 00:38:30)
Factual error: When Michael fills the tank with water (below the stock room), he then strips his clothes off, and slides down a pipe and into the water at the bottom of the tank. Since the water level was way above him, the pipe he slid down and the access to get there would have been flooded also. There was no water in the pipe he slid down, so for that area to be dry, it would have to be above the water line.
Other mistake: When Michael climbs up the rope to get to the room below the infirmary, the rope is hanging from the manhole cover, but he still manages to lift the cover whilst hanging from it. In the next shot where he looks down the manhole, it's clear that there is nothing other than the rope he could have held on to while lifting the cover. An impressive accomplishment, defying the laws of gravity. (00:38:00)
Cute Poison - S1-E4
Revealing mistake: Near the end, when Michael is unscrewing the sink before kicking the wall in, watch his hands in the foreground while he is talking to Sucre. Just when Sucre says "But what you were doing up there in the infirmary." Michael starts using his fingers to take the bolt out. You can see that there is no bolt, just him turning air, with a mystery 'unscrewing' sound effect. (00:39:35)
Riots, Drills and the Devil: Part 2 - S1-E7
Visible crew/equipment: In Riots, Drills and the Devil Part 2, when LJ's mom turns off the TV, the camera man's image can be seen in the glass next to the television. (00:18:20)
