Plot hole: When Bridgette ran through the glass and Linda and Jim were at the hospital Jim tells Linda he called her mom and told her what happened and she was coming to stay over the next day. Yet apparently her mom forgot what happened because she had her committed because Linda didn't remember what happened to Bridgette's face. Also, Bridgette was like 9. How come no-one just asked her what happened?
Plot hole: When Kale and Ashley escape from Turner, Kale tells Ashley to make sure the police come. But, when the cop comes, Ashley does not seem to have told him about what just happened, he gets killed before he can request backup, and then the police arrive right after Kale and his mother walk out the garage after defeating Turner. Why did she not inform the cop and wait all that time to call the police?
Plot hole: After Abe is shot, an ambulance shows up, throws Sherry in the back and leaves. There is no way that the paramedics would leave without first speaking to the police on site, making sure that no one else there needed medical help and confirming Abe was dead. I've ridden with an ambulance 4 or 5 times and they never stay at a scene less than 15-20 minutes.
Plot hole: How could it be that Monty could possibly know exactly that Joe and the ex-wife were driving and where they would be to time that collision perfectly? A bit odd in reality to time a plan like that.
Plot hole: When Detective Broussard is killed and Patrick was being interviewed by police (dressed in a white shirt), the interviewing police detective say "a couple of nights ago you were at the quarry." In fact it was months before when they were trying negotiate the release of Amanda at the quarry. It unravels the entire movie.
Plot hole: *SPOILER* Toward the end of the movie, Ryan Gosling goes to Hopkins' house where Hopkins is tricked into not only confessing again, but giving Gosling the murder weapon, after they are back in court and Gosling is the acting prosecutor. This would be a conflict of interest due to the fact that Gosling is a witness.
Suggested correction: First, the gun that Beachum took from Crowford's house was not the murder weapon. It was Crowford's unfired gun. He only took it out of the fear of his life. Second, Beachum entered Crowford's house with police supervision. If he plays it by the book, Crowford's confession is valid. In that case, supervising officers will stand witness, along with a recording confirming their testimony. Third, Beachum doesn't need the confession anymore. He was amply clear on that matter.
Plot hole: Time inside room 1408 moves differently than time outside it, as evidenced by the fact that Mike spends weeks or even months in what he thinks is his home in California, while in reality he is still "in" the room. The Hotel's manager states that no one has ever lasted more than an hour inside 1408. He goes on to cite many examples where the guests died after just a few minutes. No previously sane individual commits suicide after spending a few minutes in an eerie room, obviously, so the only explanation is the one offered by the "receptionist" over the phone, albeit in fewer words: guests in room 1408, while experiencing their own time frame inside the room, are in fact reliving the same hour over and over according to the rest of the world's time frame. This being the case, Mike's ex-wife should not have showed up at the climax since Mike's hour had just started over, undoing the call he placed to her earlier in the film but later in the hour. Whether or not the film makers intended this inference is irrelevant as the movie plainly lays out these conditions and must therefore adhere to them lest a plot hole be created. [This keeps being debated back and forth - ultimately there's not going to be any absolute resolution, so it's being locked down as a mistake and viewers will just have to make up their own minds - Jon.]
Plot hole: When Mr. Jeffries finds out that Evan is named August Rush too, he goes to the Central Park concert and sees Evan onstage, however he couldn't know that Evan was having a concert, or even that Evan was at that place at that time.
Suggested correction: There were streetlight banners all over Central Park with August Rush's name on them (and presumably the Philharmonic had flyers and other ads with August's name on them). So it's certainly conceivable that Jeffries recognized the name from an advertisement.
Plot hole: Brewster gives Erica his gun to shoot the last perp, but it was HER gun that shot the other two. Brewster is going to have to convince investigating officers that the one perp killed the other two...or would they even care?
Plot hole: This could be a "suspension of disbelief" issue, but at the climax of the movie when the murderer's accomplice gets shot, Jack has to grab the rope to save the dangling Dean. Objects (including people) fall at 32 feet/second, and speed up after that. That's roughly 10 yards/second, which is the speed of a world class sprinter. Jack was a speedy fellow to get to that rope, especially with street shoes, no starting blocks, and a slippery surface to boot (not to mention his age).
