Other mistake: The van used by Cecilia to chase Tom should be damaged because of the crash, but it was not.
Continuity mistake: When Cecilia is talking to Adrian at the dinner table towards the end of the movie, the food on the plate is situated differently from shot to shot as they converse.
Deliberate mistake: The suit, rather than using many large cameras, should be created with many imperceptibly small cameras in between monitors. We need monitors to see what is on the other side of the suit, not camera lenses.
Continuity mistake: Final dinner, Cecilia has a bandage on her left wrist. Then in the toilet she hasn't. Back in the dining room, she wears it again.
Continuity mistake: When Cecilia's talking with Tom in his office her hair's over the front of her left shoulder. A shot of Tom and suddenly her hair's over the front of both shoulders. A shot later it's back to being just over the front of her left shoulder.
Continuity mistake: When Adrian's throat gets slit, he is shown clutching his neck with his hand, then falls from the chair he is sitting on and collapses onto the floor. He is also shown banging his hand on the table whilst he falls over. This same moment is then shown again on the CCTV camera, but here, he is shown falling from the chair and collapsing onto the floor, all while clutching onto his neck the entire time. The moment where he bangs his hand on the table is not shown.
Continuity mistake: When Cecilia and Adrian are speaking at the dinner table towards the end, after Adrian says "I would burn everything I own just to prove that to you", Cecilia says "okay" and Adrian also replies with "okay." At this moment, Adrian's hands are placed on the table. In the next shot, Adrian's hands are suddenly raised slightly, above the table.
Continuity mistake: When Cecilia shows the champagne bottle she holds it by its neck or by the upper part, depending on the shot.
Continuity mistake: When Cecilia is at the restaurant with her sister, the position of her hands is inconsistent between shots.
Audio problem: When the invisible man slaps Sydney (making Cecilia look guilty), the sound of a bare hand slap is heard. But the invisible man was wearing gloves as part of his suit, so the sound would have been duller and blunt.
Answer: She worked as an architect before meeting Adrian.
