First Down - S2-E4
Continuity mistake: Link pulls the clip out of his pocket, and the way he holds it changes between shots. (00:39:00)
Revealing mistake: In the final scene you can see Abruzzi in his cell where they have reused shots from series 1 in Fox River.
Photo Finish - S3-E6
Visible crew/equipment: In the opening scene, a cameraman is visible behind Tracy McGrady. (00:00:47)
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)
Plot hole: C-Note says about pulling a simple bump and grab on The Key like they did before. However, when Abruzzi and his men get The Key the 1st time, C-Note wasn't in the group then. It is extremely unlikely they would divulge this trivial piece of information as the issue is long since resolved. (00:03:50)
Continuity mistake: Alexander Mahone reveals his so called past to Tweener and shows pulls out 2 pills from his pen, however next time we see the pills there are 3. (00:12:10 - 00:13:20)
Continuity mistake: In season 1 Lincoln says his mother died of liver cancer. In season 4 they said she died from a brain tumour.
Deliberate mistake: *SPOILER ALERT* Behind T-Bag is the actor who plays Lechero, and Lechero had just died in the episode. The person was not Lechero, but maybe they didn't have another extra at hand to replace him. 'Time 1' and 'Time 2' are taken from Netflix at the time this was posted. (00:29:46 - 00:30:25)
First Down - S2-E4
Continuity mistake: The front licence plate disappears from Link's car as it hits the tree. (00:03:20)
First Down - S2-E4
Revealing mistake: Throughout the entire car chase, you can see through the front window of both cars, including as Linc and Michael are run off the road. However, when the car gets airborne and hits the tree, the glass on the windscreen is now frosted up, so you can see no one is in the car when it hits the tree. (00:03:10)
First Down - S2-E4
Revealing mistake: During the car chase at the beginning, there is a shot of the cars speeding off just before we see the truck approaching. However, look carefully and you will see the truck parked up, waiting to move. (00:02:40)
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)
