The Mist

Errors in geography: The fire engine that drives past the grocery store says "Caddo Parish" on the door. Caddo Parish is not in Maine, where the movie takes place, but in Louisiana (Shreveport) where the movie was filmed.

• Continuity: The blood splatter on the windshield goes from being in the middle of the broken glass to being spread out across the windshield and then back again.
  
  
• Revealing mistakes: The fallen tree which crashed through the house of David Drayton at the beginning of the film, appears to have had it's roots cut.
  
  

• Factual errors: CMP (Central Maine Power) vehicles shown at the start of the movie should be orange, not white. In addition, Maine State Trooper vehicles are shown as being white later in the film, when they are in fact blue.
  
  
• Revealing mistakes: "The Castle Rock Times", the newspaper a shopper is looking at in "The Food House" town general store has no datum, issue number or price on it.
  
  
• Continuity: In the scene where Sally gets stung by the wasp-like creatures, the mark from the sting on her neck appears BEFORE the wasp has struck.
  
  
• Factual errors: In the scene where you can see the headlines "Electric storm largest on record" on The Castle Rock Times, the entire text underneath it is in Latin. Same for the text underneath the "Celebrating Heritage" blurb above the masthead.
  
  
• Continuity: When David is seen repeatedly beating down on one of the winged creatures in the grocery store with a mop, there is one brief camera shot that clearly shows the end of the mop still attached (it had been removed moments earlier). The next shot shows the mop without the end.
  
  
• Continuity: After the bloody scene in the storeroom, David's shirt is wet, but not very soiled. When he steps into the market, there is a large smear of blood on his shirt.
  
  
• Errors in geography: On the shelf in the store you can see bags of "Zapps Potato Chips" this is a Louisiana brand of chips and only sold in Louisiana, the movie takes place in Maine therefore, the chips should not be on the shelf.

• Continuity: SPOILER: After David shoots the people in the car, we see blood stains on the inside of the windows, which we did not see from the outside when the shots were actually fired.
  
  
• Continuity: SPOILER: After the tentacle slaps the bag boy, it leaves a noticeably bloody mark on his neck and chin which all but vanishes in subsequent shots of the doomed lad.
  
  
• Factual errors: SPOILER: The white troops on the refugee-truck in the end wear Ukrainian PGM gas masks that were used in the late 70's, but never in the US. In addition, they wear the masks with sealed filters that, of course, would deter them from breathing.
