Other mistake: Michael goes to Fox River in April. Maricruz gets pregnant in the same month. In mid-June, when Michael get arrested in Panama, she's still pregnant. That's 2 months. He was in there for about 2 weeks, due to his deal with the company. Therefore, he would have escaped Sona at the end of June or the start of July. The start of Season 4 is set 3 weeks after the escape from Sona, so Maricruz should be 3 months pregnant, but gives birth at the start of season 4, meaning that the baby is 6 months early but looks very healthy.
Continuity mistake: Season 2, Episode 10. When Michael and Sara are driving towards Mahone down Butterfield Road, both cars are seen in one shot and both cars are on a gravel road. In the next clip, seen from Mahone's end of the road, his car is on asphalt.
Factual error: Episode: Bad Blood. When the airport security guard stops to give Sucre a ride, his car has Sinaloa plates on it. Since he works in Ixtapa/Zihuatinejo, it should have Guerrero plates on it. Sinaloa is several hundred miles away.
First Down - S2-E4
Continuity mistake: During the car chase in the beginning of the episode, Bellick's car swerves to avoid hitting a truck as they go over a bridge. The next shot is from in front of the cars, and in the background you can see the bridge and a stretch of road behind it, but the truck has vanished. (00:02:40)
Revealing mistake: When Haywire jumps off the tower, it's obviously a stuntman falling down. And when you see his fall from above, he is falling towards a big drain. But when the scene cuts to the part when he has landed, he's lying on concrete. (00:42:15)
Revealing mistake: In the episode where Scofield, Sucre and T-Bag are driving in Panama, the trees in the background have no leaves - like Autumn/Winter in the US. And even though there of course are trees in Panama which shed their leaves, there is no time of year when all trees are leafless - like in the temperate zones. That shot was definitely not filmed in Panama.
Continuity mistake: This happens in the scene where Lisa is scolding LJ for getting arrested. When LJ says "I don't have a father", he is leaning on the table with his arms crossed. When the shot changes, his arms are uncrossed and in a completely different position. (00:22:25)
Other mistake: The psychologist shows Michael a photo of his family with his Mom, Dad, Michael and Lincoln but Michael never actually met his father when he was young.
Revealing mistake: When Sara crashes into the ATV to save Michael, you can see that the people on the ATV are switched out with crash-dummies.
Continuity mistake: Series 2 - Episode 10. When Sara is to meet Michael at 1681 Butterfield Road Sara looks in the mailbox. She closes the lid, yet the mailbox is seen standing with the lid a bit open. In the next couple of shots the mailbox is completely open, and when they jump in the car and leave, the lid is now closed.
The Message - S2-E15
Factual error: When Fernando Sucre steals the Volkswagen in Sinaloa, Mexico, the license plate on the front begins with F. All Sinaloa passenger plates begin with V. (00:14:10)
Visible crew/equipment: Alex finishes talking to his wife, looks outside, and in the fan you can see the face of one of the crew members.
And Then There Were 7 - S1-E11
Continuity mistake: When chasing LJ through the woods, Quinn's wounds go from his right side to his left side and back. (00:29:10)
Audio problem: Bellick gets shot in the leg and screams but in the brief shot we see his face during the sound, he isn't screaming at all. (00:23:20)
First Down - S2-E4
Continuity mistake: All throughout the car chase, the car Michael and Lincoln are in has a license plate on the front bumper. But after Bellick has forced their car off the road, the car makes a jump before hitting a tree, and while it is in mid-air you can see that the license plate has disappeared. (00:02:50)
Riots, Drills and the Devil: Part 2 - S1-E7
Continuity mistake: This happens during LJ's fight with his mom and step-dad. When LJ says "You got no clue do you?" you can see Lisa's hands on his shoulders trying to calm him down. When the shot changes, Lisa's hands are on her hips. (00:18:45)
Continuity mistake: When Sara is being tortured in the bathtub Paul Kellerman receives a call. When we see a brief clip of Sara, her hair is a lot drier than it was a second earlier.
Factual error: When in New Mexico, all the vehicles have license plates on the front. New Mexico only issues one plate, for the rear of the vehicle. Also, at least one of the plates has a Q in the serial. New Mexico only uses Q's on vanity plates.
Plot hole: In a previous episode Link says he ditched the gun after he was framed and that he chose the gun the night before. Earlier in the episode, Michael met Link off the street, then went to a bar and met Veronica, then those two go to Michael's apartment. At the apartment, Michael gets the call from Link who is trying to get Michael to talk him out of killing Stedman. But how could he choose a gun the night before when he is asked to kill Stedman and calls Michael on the same day?
Answer: Because of coincidence.
