Revealing mistake: Just after we see the inmate get stabbed there is a shot during the quick montage of one inmate holding the door, while his cellmate climbs up onto the bed for a better look at what is going on. In this very quick shot, the cell door moves despite the fact A wing is on lock down. (00:07:15)
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 1 - S1-E6
Revealing mistake: One of the rioters uses a fire extinguisher to try and break a door down. However the extinguisher is seen to bend and flex. (00:36:40)
And Then There Were 7 - S1-E11
Revealing mistake: When Nick is shot by Quinn, a blood pack is briefly visible under his shirt. (00:13:20)
Revealing mistake: Michael climbs out of the hole during the escape in his coveralls. When he looks down to shout to the others to say it's clear he has no top on. The shot is reused from when he first climbed up. (00:37:10)
Revealing mistake: When Pope bursts into the infirmary and sees Westmoreland's body, watch the collar of Westmoreland's jacket. You can see it moving up and down as though he's breathing. (00:03:30)
Revealing mistake: After Pope enters Scofield's cell to see the escape hole, we see him standing outside the cell looking out at everyone throwing toilet tissue etc. If you watch closely right after we see a guy pulling his pillows toward him to tear up, it cuts to another inmate who is throwing stuff out as well. Only thing is, we see the cell door slides to the side slightly which would indicate that the cell doors where not locked. In the event of an escape, lockdown would happen immediately, with all cell doors locked with the prisoners inside their cells. (00:04:00)
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.
Revealing mistake: When 5 of the escapees are heading to Oswego to get the supplies and Michael tells Lincoln to turn right, you can see it isn't a real car as the steering wheel doesn't turn - Lincoln just moves his hand along the wheel. Watch the grooves and you will see. (00:18:50)
Revealing mistake: Michael and Lincoln climb over the dirt pile and down to the other side. The dirt area below them has been disturbed from previous takes.
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)
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)
Revealing mistake: When C-Note leaps out of the train, you can see that the man jumping out of the train is a stuntman. He is much chubbier than C-Note (wearing a life vest) and his face is completely different. (00:22:20)
Revealing mistake: When Sara Tancredi is pulling her dead father off the door he lets out a very audible grunt and you can see his eyes and mouth moving around, a few seconds later he is on the floor and his eyes are dull and his skin slightly pasty. (00:16:40 - 00:17:05)
Answer: Don Self actually worked with Whistler before he died. And Whistler with the bird book actually knew where Scylla was.
