Plot hole: The most secure prison in the world, designed with the advanced schematics of world leading prison-building architect (J.D Ray Breslin) has cameras somehow interconnected to one another so tightly that physically neutralizing one puts every other camera out of commission as well.
Plot hole: The Tomb is supposed to be a top-secret off the grid prison that nobody is supposed to know about yet the schematics for the place are conveniently left available online such that a hacker can search for it with no problem, on top of that the fact that it's known on the outside world as "The Tomb" suggests it's more well-known to people that it should be.
Plot hole: In this top level state-of-the-art security prison with transparent walls, cameras everywhere and no civil rights concerns since it's all illegal, there's not a single hidden microphone in the communal parts. Even worse, the wardens never search the inmates, who can smuggle freely all sort of stuff, sometimes in the most blatant way (like when the protagonist gets stitches for his leg).
Plot hole: In the Bendwater escape, the security cameras show the time outside the prison as 15:59, but a few cuts later, there's a shot of Stallone in his cell with the timecode being 15:56. That's not a continuity mistake, since it turns out that Breslin rolled back the security monitor, the problem is, he is shown doing that at 15:57, and barely rolling the tape past the point when he stands up. By the time the guards are looking at the monitor after 16:01, the tape showing him nice and quiet 3 minutes before would have already rolled to the incriminating part where he breaks out of the cell. (00:06:50 - 00:13:25)
Plot hole: Breslin is supposed to going to an off the grid prison, a place nobody is supposed to know about outside of the prison except for Clark, who is the only one who really knew where Breslin was being sent. So why in the world would there be a warden as the "contact on site" that Breslin would inform if things didn't go well? It also makes no sense that Breslin would have an evacuation code when his own people have absolutely no idea where in the world he could possibly be.
Chosen answer: He says "Ich reiss euch eure Augen raus!" The full text from when he starts speaking German is "Ich kann's nicht aushalten! Arrgh! Ich kann es nicht mehr aushalten! Ich kann nicht mehr! Helft mir. Hoert auf mich zu quaelen. Ich Kann Nicht Mehr!" At this point Stallone opens the tunnel and focus is back on Schwarzenegger. "Ich kann das nicht mehr aushalten! Ich halte die Hitze nicht mehr aus! Ihr bringt mich um! Helft mir! Hoert auf mich zu quaelen! Hoert auf mich zu quaelen! Ich sterbe! Ich kann nicht mehr!" Here camera malfunction is detected. "Mein Herz!" Short break while others are yelling. "Ich hoere euch. Ihr Schweine! Ich hoere euch! Ich bring' euch alle um! Ich reiss' euch eure Augen aus! Ich schneid' eure Eier ab und stopf' sie euch in den Arsch! Oh ja, da sind Sie, oh ja!" Lights are switched off. "Oh nein! Nein! Ich fürchte mich vor der Dunkelheit! Ich habe Angst!" Warden enters the box. "Oh Gott, bitte hilf mir!" Here he starts praying The Lord's Prayer. "Vater unser im Himmel, geheiligt werde dein Name, dein Reich komme, dein Wille geschehe, wie im Himmel, so auch auf Erden. Unser tägliches Brot gib uns heute, und vergib uns unsere Schuld, wie auch wir vergeben unseren Schuldigern, und führe uns nicht in Versuchung, sondern erlöse uns von dem Bösen." He starts yelling again. "Du bist der Böse! Du bist der Teufel!" Stallone climbing, then back to Schwarzenegger. "Habt ihr nicht von jenem tollen Menschen gehoert? Der am hellen Vormittag eine Laterne anzuendete und auf den Markt lief und unaufhoerlich schrie 'Ich suche Gott! Ich suche Gott!'" Translation is: "I can't endure it! Arrgh! I can't endure it any more! I can't endure it! Help me! Stop torturing me! I can't take it any more!" At this point Stallone opens the tunnel and focus is back on Schwarzenegger. " I can't take it any more! I can't bear the heat any more! You are killing me! Help me! Stop torturing me! Stop torturing me! I'm dying! I can't take it any more!" Here camera malfunction is detected. "My heart!" Short break while others are yelling. "I hear you. You pigs! I hear you! I'm going to kill you all! I'm going to rip out your eyes! I'm going to cut off your balls and shove them up your asses! Oh yes, there you are, oh yes!" Lights are switched off. "Oh no! No! I'm afraid of the dark! I'm afraid!" Warden enters the box. "Oh God, please help me!" Here he starts praying The Lord's Prayer. Then he starts yelling again and points at the warden. "You are the evil one! You are the devil!" Stallone climbing, then back to Schwarzenegger. "Didn't you hear of that great man? Who lit a lantern in the bright morning, went to the market place and yelled non stop 'I'm looking for God! I'm looking for God!' "
