Continuity mistake: When Peter is on the freeway thinking of changing into the left lane, the vehicles are different between the shots of his face and the shots looking ahead. Then when he changes lanes there was a Mitsubishi Mirage in front of him and a blue Dakota truck a few cars ahead, yet both are gone when we see the lane he left begin to move. Then when he changes back into the right lane, we see a motorcycle up ahead in the lane he left, yet in the next forward shot, the motorbike is gone. (00:01:05)
Continuity mistake: When Bill Lumbergh pulls into his parking space at Initech, the sign reads "Reserved for Bill Lumbergh, Division V.P." When Peter later pulls into the same space the sign only reads "Reserved for Bill Lumbergh." (00:02:50 - 00:41:05)
Continuity mistake: In the scene with Samir, Michael, Peter, and Tom in the office talking about Tom's 'jump to conclusions' mat, the army men in the background on Peter's cubicle change positions. Shots of Michael show the kneeling man with the bazooka on one side of the minesweeper, shots of Peter show them in reversed positions. (00:12:30)
Factual error: All of the computers show a Mac OS when they're booted up. However, when Peter is shutting his computer down to try to escape his boss, the computer shuts down to a C: prompt. For those not technically minded, a C: prompt is only seen on IBM-compatible PCs, never on Macs. (00:19:20)
Other mistake: Peter is playing "Tetris for Windows". We saw earlier that the computer's UI was Mac-like. (00:19:20 - 00:43:45)
Continuity mistake: When Peter goes to see the Bobs for the first time, he comes in, there's the Bobs sitting on the right side of the desk, and the row of empty chairs on the left. One of the chairs is not pushed in and turned left but when Peter comes back to sit down after getting his water it is pushed in and straight. (00:34:55)
Continuity mistake: When he is playing Tetris, he is playing a different game every time. (00:43:35)
Continuity mistake: During Tom's BBQ when Michael Bolton and Samir are asking Tom's lawyer about prison you see Michael lose grip and drop his cup with a piece of ice hitting Samir in the head. When the ice hits him he's holding the cup in his left hand but when the camera angle changes the cup shows up in his right hand. (01:01:30)
Continuity mistake: When Lumbergh is talking to Milton in the basement, he is finishing his piece of birthday cake. He throws the plate out in a nearby garbage can, then suddenly has a cup of coffee in his hand, when Dom comes running after him. (01:09:45)
Continuity mistake: In the scene near the end of the movie where Peter apologizes to Joanna, Joanna is shown either in her red shirt and holding her blue jacket, or wearing her blue jacket. For instance, as Joanna is moving in to kiss Peter, she is holding the jacket, but as they embrace, she is wearing it. In the blue jacket cuts, it is much less windy, and Joanna's hair is styled differently than it is in the red shirt cuts, where her hair is blowing due to the wind. (01:16:20)
Continuity mistake: In the scene when Peter returns to the company and sees that it's on fire, his hair is coiffed and partially in his face. In the next shot, as he watches Milton skulk away, his hair is cut short and totally out of his face. (01:20:20)
Continuity mistake: Toward the end of the scene where Michael, Peter and Samir are smashing the printer, the camera pulls back to show all the printer's parts around it on the grass, and its cover is off. When Michael goes back for one more blow, the printer's cover is still on it.
Continuity mistake: In the restaurant scene the volume of the water in the glass in front of Jennifer Aniston continually changes from full to half-full depending upon whether Aniston or Livingston is talking.
Continuity mistake: When Peter is shutting his computer down to try to escape his boss, one of the cuts shows that it's an Optiquest monitor (us computer people will recognise this), then they cut back to Peter, back to the monitor and there's a piece of black electrical tape covering up the company logo on a completely different monitor.
Continuity mistake: In the scene where Lumbergh is talking to Milton in the building basement, his ever-present cup of coffee switches hands between shots.
Continuity mistake: In addition to the mistake about Joanna's hair on the way back from the party: on the way TO the party, when the camera is on Joanna her window is up and her hair is still. But when the camera is on Peter, Joanna's window is obviously down, because her hair is blowing.
Continuity mistake: When Michael gets pulled away from beating the copier, he has a cord in his hand which he drops before going back. They pull him away again and the cord is gone, but in the last shot it in his hand again.
Continuity mistake: When the guys go to Flinger's for coffee, we see that the little cardboard triangle thing in the middle of the table advertising new additions to the menu (most restaurants have these) is facing the camera with 3 lines of text reading "Try our Jalapeno Poppers." In all the shots with that triangle thing in it after that, it has 5 lines of text facing the camera reading something different.
Continuity mistake: In the scene where Michael and Peter are in Michael's apartment, sitting and talking, we see Michael has a blue shirt which is spot-free. Right before they cut to the scene at the bar, we see that he has 2 small stains on the upper right of his shirt.
Continuity mistake: In the scene where they are smashing the copier, they show a slow-motion of Samir lifting his right leg to smash the copier, the camera cuts away and then comes back showing him coming down with his left leg instead of his right.
Chosen answer: I think the hypnotism broke something instead of putting him into a trance. It totally released his stress, that stayed despite not being influenced by the hypnotism anymore.
