When Dalton takes off the knife he gives Frankie a tape to hold, the tape appears and disappears from his hand several times.

When Ben is receiving his shave on board the boat, the amount of shaving foam on his face changes between shots.

After Dalton's car accident with the train the piece of paper with Ellie's number is still at the same spot (right in front of the windshield) where he left it before the crash. Even after several spins of the car.

Dalton gets into an accident with a train, after the train hit him and sends his car spinning around, you can see the wheels throwing sparks from the tracks. This has been proven that even in Full Emergency Braking, train wheels do not lock up and send showers of sparks like portrayed here.

When Dalton assaults the Sherriff's deputy on the beach, he quickly grabs the cop's gun out of its holster and uses it to knock the officer out cold with one clean blow to the head (of course). Police officers' holsters are required to be level 3 duty holsters, which make it very difficult to impossible for anyone besides the officer to remove the weapon. Even if Dalton was trained up on such holsters, they are all different and cannot be defeated so easily.

"WYBS 106.4 for the Florida Keys .... and 102.8 in Key West". Both frequencies end with an even number. However, all FM stations in the USA are assigned to frequencies that end with an odd number. But, I guess it's possible that 106.4 and 102.8 may have been used to avoid confusion with actual FM stations.

Dalton is told there is a hospital about twenty-five miles from the fictional Glass Key. The Road House in the movie, as stated in the film, is near mile marker 77. There is Mariners Hospital at mile marker 91, about 14 miles, or about 23 minutes away.

Dalton is told the hospital is about 25 minutes away, not miles.

After getting a beat up from his girlfriend's corrupt cop father,she gives Dalton a ride and tells him to leave West Key.West key does not exist,the city name is Key West in Florida, location of the entire plot.

As stated in the movie, the Road House bar is near mile marker 77 of the Florida Keys. This means that a Greyhound bus coming from mainland Florida would not cross the "7 mile bridge" for customers going to "Glass Key". Thus, they could not observe "Fred the Tree", an actual tree, that lives between mile 40 and 41 on the bridge. This would not be characterized as an error more as artistic license for the story...

While traveling down to the Keys, Elwood is seen driving over the 7 mile bridge. When he gets into "Glass Key" he meets a girl at a bookstore who greats him. They are at Mile Marker 74-77, somewhere in there, The 7-Mile Bridge is located at Mile Marker 40-47, so he would be at mile marker 40 or less if this were correct.

A "collect" call from the FL State Penitentiary would not show up as Dad on the phone because it would go through many different phone company switchboards. It would never come from the same number repeatedly.
