Plot hole: At Tim's funeral, Olivia's attorney tells her that Tim had himself removed from Olivia's Last Will and Testament, proving he loved her and didn't want her money. However, an attorney could not legally change a client's Will without that person's knowledge and drafting a revised version.
Suggested correction: Not true. Anyone can have themselves removed as a beneficiary of a will. This is done by signing an Affidavit of Disclaimer of Inheritance at such time as someone becomes aware that they have been included in a will as a beneficiary. This is what Tim meant when he said he had removed himself from Olivia's will.
Plot hole: If the vacuum is strong enough to suck up a hand grenade, why isn't it sucking up the ampules?
Plot hole: Derek, who escaped the mental hospital by pretending to be his twin brother Tyler, was able to locate Tyler's vehicle by using the keys to beep its horn. Once inside the SUV, he apparently found Tyler's cell phone, which is odd because most people carry their cell phones with them. But Derek did not ask Tyler for his cell phone's password before rendering him unconscious - so how did he gain access to the cell phone without the password? (It isn't likely that Tyler previously gave it to him). (00:20:40)
Suggested correction: Tyler never left his cell phone in the car. He had with him when visiting Derek. We see him pull out his cell phone to show Derek a picture, so the phone was already unlocked, assuming he locks it with a password in the first place.
I haven't had time to finish posting the rest of the mistakes I have, but I just uploaded two that should show up under "pending submissions." They probably should have been posted before the one above. I suppose the real question is where the cell phone came from each time.
Plot hole: Spoiler; Under the pretense to help catching the murderer, the Judge goes through great lengths to enlist the help of the doctor to fake his own death. In this adaption it's made moot by the fact that the murder happens in the living room, his body needs to be carried upstairs and we even see that happen, with all the remaining survivors hauling the 'corpse' in their arms. One thing is faking with a little make-up (literally a paste-on red dot) to be shot in the head, with just the accomplice examining the supposed corpse, and the others at distance and with bad lighting. But with everyone carrying the body, including a police inspector and a PI who are accustomed to violence and real murder, it's plain impossible.
Plot hole: In the beginning, Charlotte insists to Velma that cousin Miriam is coming, but Velma says "She's never answered any of your letters." And Drew says she's not coming. But when Miriam does come, only seconds later, Velma and Drew now act like they were expecting her. Velma says "You nearly beat your telegram. We weren't expecting you till tomorrow." It's like the film has been badly edited, with Miriam's announcement of her arrival ending up on the cutting room floor.
Plot hole: Tony said, "If Danny beat him [Kevin] any more, he would have never lived" and Kevin spent a month recovering in the hospital. Tony and Danny were "advised to take a plea" and agreed to 10-25 years in prison. When Kevin went to the correctional facility to "forgive them in person", Kevin said, "We never properly met. I was in the hospital during your trial." Guilty pleas do not result in a trial and a felony criminal case would not be resolved within 30 days of the commission of the crime. (00:44:50 - 00:49:06)
Plot hole: This observation regards a computer whose memory architecture is on a physical scale (e.g., size) that allows multiple humans to enter and maneuver within it. With electronic components, scale imposes a design limitation such that the greater the distance between components, the more time is required for a signal to traverse between components. This computer's massive size would assure substantial performance limitations which are inconsistent with the plot line of the computer's overall power.
Plot hole: Regis could have saved himself a lot of time and solved the case much quicker if he had just verified the entries in Carla Town's day planner with the businesses listed. A few phone calls would have told him the entries were forgeries without going to the technician for help.
