Continuity: The position of the ‘rope’ of clothes on which Simon is holding changes. In one shot he is holding onto a particular part of a shirt, but in the next he’s holding onto a different part.

Visible crew/equipment: When Maguire raises his hands together to say the prayer, you can see the black wire of a microphone, running up into his shirt.

Revealing: When Colonel Maguire is hitting the walls with his suitcase, there is a shot where the suitcase is coming towards the camera. Dust and stains reveal the protective glass that is in front of the camera.

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.

Continuity: 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.

Continuity: When Simon and Kate get separated the first time Kate opens the door and lowers her hand. When it cuts she still has her hand up.

Continuity: When Kate figures out the '60659' mystery, when she looks at the watch you can briefly see it reading 6:06:15, then in the next shot, the watch is now reading 6:06:02.

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.'

Continuity: 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.

Continuity: After everyone releases the colonel from his belt and lay him on the floor, Simon takes out his identification. Between a wide shot to a closeup, the top of the colonel's shirt goes from being tucked under his tie, to being untucked from under it.

Visible crew/equipment: When we first see Kate, she opens a door, and then, she climbs through. As she climbs through, you can see down her blouse, and you can see a microphone.

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.

Continuity: During the movie, Max's shoes change, and they obviously can't because he's trapped in the hypercube. When helping the colonel who's hanging himself, you can see Max's shoes are black, but then later on they're blue. This is most noticeable in the scene when Max and Julia are talking, and Max throws his shoe across the room.

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.

Continuity: When they find the dead scientist, Kate helps Sasha put her left foot on the ladder twice.

Continuity: 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.

Continuity: Throughout the movie the blade on Simon's knife changes. In some shots it's a double straight edge blade, in others it's serrated on one side.

Continuity: The blood that Simon wipes off the knife onto his hands disappears instantly.

Continuity: When Kate turns to see all the numbers appear on the silver frame around the portal, although they are meant to be in the same position and handwriting as when they were drawn, much of the writing is not.

Continuity: When Sasha is trapped in the Razorsphere room, she yells “Kate, help,” and then between three shots her necklace changes from tucked under her purple shirt, to hanging out and back to tucked under.
