Corrected entry: It's obvious the fat American man was played by a European because of the way he pronounces "been".
Corrected entry: The character Eirik gets shot in the eye with a blank by Ray. From this point on he is blind on one eye. Later in the film (at most one day later), he sees Ray sitting with Chloe on a terrace. He then runs to the tower where Harry is and jumps over a rope that hangs 40 cm high. For someone who was shot in the eye a day before, he could see pretty well and was fairly agile.
Correction: How does being blinded in one eye affect your ability to jump over a rope? It doesn't. As for the rest, he still has one functioning eye - he'll have to be more careful in what he does, but he can still see.
Corrected entry: When Ken jumps from the bell tower, there are several problems. One, he could barely move from the loss of blood and then stands up to jump. Two, he drops the coins from his pocket into a crowd and then jumps into an empty space. Three, he jumps face forward - which would mean he would land perpendicular to the building - however he landed parallel to the building. Four, he was conscious and talking after a fall from that height onto bricks.
Correction: One, it was a last ditch effort using all his strength. It hurt to walk because his knee had been shot, it wasn't the blood loss that incapacitated him. Two, he drops coins into a crown to clear the crowd out. It shows them all stepping out of the way of the falling coins and looking up to see what's going on. That's why he dropped the coins. Three, his body rotated as it fell. Four, not impossible. A woman recently survived a fall from an airplane onto a paved parking lot. If she could fall from that height, there's no reason Ken shouldn't be able to be alive and speaking after his fall.
Correction: That cannot count as a mistake, its merely someone who was large enough for the characters to mention he should not go up the bell tower.
