English, Fitz or Percy - S1-E5
Continuity mistake: When Michael is supposed to be in Pope's office holding the support for the Taj Mahal so it didn't come unglued, Abruzzi placed the makeshift key in the lock of the door, allowing Michael to escape to get back with the other inmates. When Michael opens the door and it's unlocked, The Key is in the deadbolt. As he shuts the door behind him, The Key is in the lock of the door knob. (00:23:20)
And Then There Were 7 - S1-E11

First Down - S2-E4
Continuity mistake: Bellick's partner, Geary, is wearing a light grey T-shirt, with a very prominent sweat stain on the front. Throughout the episode, this stain constantly changes shape and size, even within two shots of the same scene, and sometimes it disappears altogether.

The Old Head - S1-E8
Continuity mistake: In the scene where LJ comes to visit Lincoln and admits to breaking the coffee table, LJ's hand moves between shots. When Lincoln is shown, you can see LJ sitting in front of him with his chin resting on his hand. When the shot changes to close-ups of LJ, his hand is down and completely out of the shot. (00:08:10)
Continuity mistake: In Episode 14, "The Rat", when Lincoln and Dr. Tancredi are in his cell together, he says "How it gonna feel when they tighten the belts". He then turns his head so that he is looking the doctor in the eyes, but when the angle changes, he is staring directly in front of himself, and his head is not turned at all.
Continuity mistake: When Steadman takes out his gun, he presses it to the back of Veronica's head. She does not flinch or shy away from the gun, but in the next shot, a close-up of Steadman, the gun muzzle is pointed at the camera with Veronica off-screen, and so the gun is suddenly not touching her. (00:22:40)
