Plot hole: We see Michael wearing the mask throughout the day, from morning at the Myers House, to mid-day outside Laurie's school, to afternoon when Tommy is leaving school, yet when Laurie and Annie see the sheriff in front of the hardware store on the way to their babysitting jobs (presumably in late afternoon or early evening), the store's alarm is still ringing and the sheriff mentions that one of the items stolen was a Halloween mask.sam norton
Plot hole: According to the denouement sequence shown in the film, Linnet Ridgeway is shot asleep in her bed approximately three minutes after retreating from the lounge. Less than 2.5 minutes pass from the moment Linnet leaves the lounge to the moment when Doyle is left alone by the other guests. It takes another 30 to 45 seconds for him to pick up the pistol, rush into his cabin and kill his sleeping wife. How could Linnet have walked to her cabin, taken off her jewelry, changed into her night-dress, retired to bed, and fallen asleep in 180 seconds?
Plot hole: At the Jefferson Institute, to evade the security guards, Dr. Wheeler climbs into the space above the ceiling, crawls over the air ducts, then onto a catwalk, and finally escapes lying atop an ambulance heading to the airport, then immediately goes to the hospital to warn Dr. Harris. Throughout this entire ordeal she never gets disheveled, nor does her white doctor's uniform ever get dirty or wrinkled. She is perfectly clean and groomed.raywest
