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.
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.
Answer: Wealthy Adrian controlled every aspect of Cecilia's life, so he most likely prohibited her from working - she was his stay-at-home "trophy wife." Cecilia asked "invisible" Adrian, "So why me? I'm just a suburban girl who stumbled into your life one night at a party... There's nothing left for you to take. You've already taken it all", which implies even preventing her from getting employment or starting a career. Cecilia did graduate from "Cal Poly Architecture", so she had skills/ability (evidenced by her portfolio of drawings), but she was stuck at the "aspiring architect" level. She told the job interviewer at "Ruler" architecture, "After Cal Poly, I worked in Paris for six months." That's the extent of her employment history - Adrian took over her life after that. There were no indications in the movie that Cecilia was employed when she finally left Adrian. It appears she just took the first step toward starting her career now that she had (or thought she had) her freedom back.
