Question: How did Cecilia get an invisibility suit?
Question: Why are Cecilia and her sister Emily so distant?
Answer: From what I could see, it was never specified what caused their strained relationship. Many sisters just don't get along for a variety of reasons-jealousy, resentment, rivalry, personality clashes, etc. Of course, it serves the plot and is a common movie trope that Cecilia has little family support to help with her situation, adding to the suspense as she tries to escape Adrian on her own.
Answer: Controlling husbands like Adrian severely restrict who their wives can see and talk to, so Adrian most likely interfered with Cecilia maintaining a positive relationship with her sister. Cecilia's sister probably did not know how controlling and manipulative Adrian was, so assumed it was Cecilia who did not want to be close to her. Adrian made it appear as though it was Cecilia's choice, but it was actually the restrictions he placed on Cecilia that caused the strain between the sisters.
Answer: Because an email was sent from Cecilia but really from Adrian (the invisible man) saying that her sister was suffocating her. And that Cecilia didn't want to see her anymore.
And these were the types of stunts Adrian had been doing for years, creating tension and causing spite between the sisters.
Question: If she thought Adrian was dead, why didn't she immediately go back for their dog? She seemed to care for it at the beginning of the movie. When she goes back to the house, the dog is there, obviously in good health, who did she assume was taking care of him?
Answer: It's unknown, but having been so traumatized and terrified by what happened, Cecelia wasn't thinking logically and it probably didn't immediately occur to her. Returning to where one was mistreated and was essentially a prison would be difficult. Considering Adrian's wealth, position, and his large estate, she would know if there were others there, particularly after his supposed death-Adrian's brother, company employees, lawyers, security personnel, servants, etc. that would care for the dog. Cecelia didn't seem particularly attached to dog and she was mostly keeping it calm and quiet while attempting to escape. Also, Cecilia believed Adrian faked his death and she wouldn't risk returning.
Question: How can Sydney believe that Cecilia actually hit her when the latter was barely near her?
Answer: Sydney was upset and reacting irrationally. Being that she is still quite young and not yet fully in command of her emotions or reasoning, she reacted immediately and jumped to what seemed a logical conclusion. From her point of view, there was nothing else that could have hit her.
Question: After faking his death, why would Adrian leave Cecilia with five million dollars?
Answer: Apart from having the money to do so and portraying himself as a loving and caring husband, it was another one of Adrian's mind games and way of "screwing with her" - if she committed a crime or became mentally impaired, she would lose the trust. Adrian already had a plan to make her "lose her mind" and commit violent acts with plenty of witnesses, such as slitting her sister's throat in a crowded restaurant.
Answer: So the police would believe she killed him for his money.
Question: When is Adrian dressed up as The Invisible Man and when does Tom take over?
Answer: According to the director, it's almost always Adrian, except for the climax, where it is explicitly shown that Tom is wearing the suit. Adrian had him take over knowing that there was a very good chance Tom wouldn't survive, because he wanted to set Tom up as the fall-guy for him. (Of course Tom didn't know this).
Where does the director state that?
In an interview with Perri Nemiroff, director Leigh Whannell said Tom only wore the suit once. https://collider.com/invisible-man-when-is-adrian-wearing-the-suit-explained/?fbclid=IwAR0FeHR0w-7DPFjFq71By1SEN9e8C5tR_WPDWGQp26Rm9_ASasjqjMLKKMI.
Thank you.
Question: How did Cecilia manage to change so quickly during that final dinner, especially after she put on the invisibility suit, killed Adrian, then changed back into her little black dress so quickly? I would image the suit would have been so difficult to wear and remove. (01:13:00)
Answer: A couple things... when she pulled the mask off Adrian's brother earlier, the suit seemed pretty thin and flexible, so I can't imagine it's all that difficult to put on and remove. It'd probably be like slipping on some coveralls. It would defeat the whole purpose of the suit if it was hard to put on, wear and use. I also don't think she necessarily needed to take the time to completely change. Her dress is small enough that she could honestly probably just slip the suit on over it. Finally, it's really not uncommon for movies to "compress time" a bit by cutting scenes shorter. You could easily make an argument that we're simply not seeing everything in "real time." Why waste an extra 30 seconds just showing Adrian lying on the floor bleeding? It'd totally kill the pacing of the scene.
Question: How come the footage from the security cameras in the restaurant and the mental hospital haven't been looked at when Emily was murdered and all those guards were attacked? They all could've proved Cecilia's claims.
Answer: It's entirely possible that there weren't any security cameras in the restaurant that would have her on camera. As for the mental hospital, it doesn't really matter whether they look at the cameras or not - there are now plenty of witnesses to back her up, as evidenced by the fact she is free at the end.
Question: How long has Cecilia been away from Adrian after her escape? Had to ask because the nurse said to Cecilia that she had been pregnant for around a month.
Answer: Using context clues from the movie, we can assume she's been gone for a few weeks. She likely got pregnant shortly before she escaped, hence she's about a month along when she goes to the doctor. The events of the movie transpire over a relatively short period of time, so it all lines up pretty well.
Question: Who was Cecilia before she met Adrian?
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.
Question: How does Adrian's invisibility technology work?
Question: What is the nature of Adrian and Tom's relationship?
Answer: Tom is Adrian's brother and also acts as his attorney. He apparently helped stage Adrian's fake suicide, then acted as the intermediary with Cecilia regarding Adrian's will. Tom also acted as Adrian's accomplice by impersonating him when he wore the invisibility suit. Adrian later frames Tom to be the "fall guy" for his crimes.
Answer: Cecilia went over to Adrian's house and found another invisibility suit.
