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: Blore's death is fairly absurd, since the killer couldn't plan that he'd be standing, with all the possible room outside of the house, exactly in that spot at that distance from the window, with a ton of bricks that are precariously balanced on stone spheres that survived storms and heavy winds but somehow are loose enough to require a gentle push to fall down.
