Plot hole: Delores is walking into the murder scene at the beginning of the movie just as Ernie is shot. Later, while she is being questioned, she tells the two detectives what the thugs said and did, yet, she was not eavesdropping or looking through the door.
Plot hole: Goldie Hawn's character obviously has lost a large piece of her spine when being shot, as seen through the hole in her body. So how does she keep her upper body up straight? When Meryl Streeps character broke her neck she couldn't keep her head up, so why can Hawn walk around as normal?
Plot hole: At the end of the movie, when Lonette comes across Frank's dead body, she asks Nails what happened. Nails tells Lonette that he was pushed off a building by Holly Wood. Lonette then asks if Holly was in doodle form when she killed Frank. Nail says she was. There would be no way for Nails to know either of these things as he was trapped in the fountain pen when Frank died and wasn't released until the Spike Of Power was removed.
Plot hole: The sheer distances Kevin covers on foot in one night are outrageous. Between 9pm and midnight he walks from Carnegie Hall to the children's hospital, to 95th street, back to the toy store carrying a large paint can and a large 2x4 (street signs here put it around 59th and 5th), back up to 95th, then all the way back to midtown, to Rockefeller Plaza. One way from W 95th street to around E 59th and 5th Ave. is at least an hour on foot for an adult, he does this 4 times between 9pm and midnight, once while carrying a 2x4 and paint can, once while being chased by 2 adults, and he still has time to set up a house full of traps.
Plot hole: When Daniel is in the air with the stolen plane from the Los Alamos air base Nat suddenly appears from behind. However, Nat had no chance to slip into the plane secretely as there was only one stepladder that had been in his mom's full view while she hugged Daniel good-bye. (01:25:30)
Plot hole: When Wayne and Garth are trying to get Mr Big to hear Cassandra's band, they refer to when they spoke to the security guard earlier in the movie. They claim he said Mr Big would be in Chicago on Friday when he actually didn't - he never mentioned a specific day at all and just said he was travelling that way next week. (00:59:50 - 01:12:40)
Plot hole: Sidney's friends at the beginning act like if he made his fifth shot, he beats Billy. If Sidney had made the fifth shot, he would have merely tied Billy and they would've either gone to a playoff or just settled for a tie.

Plot hole: Just after Snyder escapes the FBI sting, he is yelling at Brown about the FBI cop being Sam Douglas. If Snyder knew the guy standing outside the car is his former partner's son-in-law, why did he continue with the business transaction as though he had never before seen and/or met Sam Douglas?
Plot hole: While we never see Lisa leave the courtroom at the end to call Judge Malloy to send the fax verifying Jerry Callo, it is possible she snuck away for a minute to do it after the dismissal and before they leave the town. However, Vinnie does not ever seem to mention that he told the judge he is Callo to her so how did she know? He must have mentioned it to her while they were rushing to leave, they were back on speaking terms and she called Malloy.
Plot hole: After Captain Ron gets fired, Martin mentions seeing Roscoe. How does he know who this person is? This is the first time we've heard Roscoe mentioned in the film. Sure we are then shown that Roscoe is the pimp for the prostitute but how did Martin know who he was?
