Continuity mistake: As everyone leaves the Razorsphere room, Julia leaves her high heels on the floor. Later on in the movie we see as she climbs through a portal, she is holding her heels. In the next shot they vanish. (00:53:20 - 01:02:55)
Continuity mistake: When everyone climbs out of the 'Razorsphere Room' Sasha cowers in the left corner of the side of the room opposite to where everyones climbing out. But you can see in the wide shot when Jerry gets killed by the Razorsphere, Sasha is now in the right corner of that side of the room. (00:53:05 - 00:53:50)
Other mistake: When Max looks into the room with Julia, we see her lying on the ground from the perspective of the original room. But when Max enters the room, we find out that the room's gravity is different, meaning Julia should really have been lying on the wall, by the perspective of the original room.
Other mistake: This occurs during the scene where the group has just rescued the colonel. Before Mrs. Paley makes her appearance, the others notice the panel opening, and make movements, but they don't make sense. We'll call the side where the colonel was the north. Sasha is in the southwest corner, and Max is near her. Simon and Jerry are both at the north wall. When the sound of the door opening is heard, Max looks to the west. Simon is kind of in a strange position, but looks correctly to the north, where Mrs. Paley comes from. Simon and Jerry both knew where to look before the door opened, so it's reasonable to assume that it's easy to tell which door is opening, so Max shouldn't have looked at any other door.
Continuity mistake: When they find the dead scientist, Kate helps Sasha put her left foot on the ladder twice. (00:38:05)
Continuity mistake: After Kate has told Jerry Sasha is blind he says "Oh, bummer, to be blind in this place," then he looks up. When it cuts, he looks up again. (00:12:05)
Audio problem: When Kate ventures into another cube room, searching for Max because he appears to be moving from door to door very quickly, she climbs through the door and says "This guy sure moves quickly, he's just..." in a wide shot, but her mouth doesn't move at all. Then in the next closeup of her, she manages to move her mouth to the word 'gone.' (00:09:50)
Visible crew/equipment: When Simon shouts to Kate "You're a dead woman!" because she goes back to rescue Sasha from the Razorsphere, the door shuts in his face, and you can clearly see the camera crew reflected in its shiny surface. (00:54:00)
Audio problem: When Jerry opens one of the doors, he sees Max holding up the colonel who hung himself. Max shouts "Help Me!" And you can clearly see his mouth never moves when this is said. (00:13:20)
Continuity mistake: When Jerry is telling about the last thing he remembers was going to sleep we can see Simon's jacket hanging on the handles. When it cuts to a close-up of Jerry the jacket is gone. (00:32:30)
Other mistake: At one point, when entering a room, Jerry says that the gravity is changing. This is completely false. The camera moves around, supposedly in a manner to reflect the changing gravity, but if you follow logic and the motion of the camera, the gravity in the room is the exact same of the room that they just left.
Visible crew/equipment: At one point when everyone is escaping through the doors away from the moving wall, when Simon is the last one to climb through the door. When the door closes we can see a persons arm reflected in the door. That is an impossible position for any of the others to stand in, so it has to be a crew members arm. (00:22:15)
Continuity mistake: When Simon and Jerry are holding Colonel Maguire and Simon says "Look at his hands. Cigarette burns." First Maguire has his hand down, but when it cuts he is holding it up. (00:15:40)
Continuity mistake: When Simon has Mrs. Paley tied to a ladder rung, prior to the slivers of light coming, Simon has two large sweat patches on his grey tee-shirt. Yet when he climbs out of the portal door, away from the slivers of light, the sweat patches have gone in a matter of seconds. (00:59:45 - 01:01:10)
Continuity mistake: Simon ties up Mrs. Paley to the ladder with his belt and threatens to kill her. Then slivers of light start to come out the wall, and he releases her hands from the belt, and chucks it to the floor. Between shots the belt moves and also disappears, only to reappear again. (01:00:20)
Continuity mistake: When Kate figures out the '60659' mystery, in the background you can see Sasha laying on the floor dead. Her hair is covering her mouth, but in a later shot, when Kate takes her necklace, her hair has moved to covering her eyes. (01:21:35 - 01:22:30)
Visible crew/equipment: After solving the "60659" mystery, Kate opens a portal, revealing nothing but darkness outside it. It then cuts to a shot of the watch ticking, then back to Kate who is still kneeling down. In this shot you can clearly see down her blouse, and the long black mic wire and mic is very visible. (01:22:45)
Visible crew/equipment: When Julia and Max are talking about Alex Trusk, Max then goes on to tell Julia that he designed the concept for the variable time-speed rooms. As he walks across the room, exclaiming "It was for a game! Now here we are!", watch the floor to the right of the screen, and you can see some black crew equipment laying there, which is nothing that belongs to Julia or Max. (01:08:25)
Other mistake: When Max looks into another room to see Julia for the first time, he starts to enter the room. He is caught off guard by the gravity shift and almost falls into the room, but is able to grab on the rungs before falling. The way the rooms are built, it would be nearly impossible to do this given that the rungs are recessed around the frame of the door. Max would first of all have had to know that the gravity would shift, and then carefully reach both of his hands around the door in an extremely uncomfortable position to be able to touch the rungs, and would even be able to grasp them until he was actually falling. There is just no way that all of this could conceivably occur as it did. (00:29:00)
Revealing mistake: The way Jerry comes into play is problematic. He is shown coming up from the bottom of the room where Kate has just met Sasha. He appears to be climbing upwards, which suggests that the gravity in the room that he is leaving is the same as the one that he is entering. However, the way that he positions his body around the square opening doesn't make sense. He turns around to see the girls. At this point, it would be very difficult for him to stay up, because he no longer has support like he did when he first came up. This shows that the actor was standing on something.
Chosen answer: Blind people use computers all the time. There are Braille monitors that interpret the visual images on the screen into Braille. They can also use speech synthesisers to convert the images into audible information.
