Other mistake: At the beginning of the movie, a woman runs to the store to get help. She uses the pay phone booth outside. The UFO takes her and the whole booth. A minute later, the booth crashes back to Earth. The next morning, the sheriff finds her wallet in the debris. She wasn't carrying it and didn't have a purse or pockets.
Other mistake: Mason Sr spends time with Sam and Mason every other weekend. After going to the Butterfly Center, they tossed a football and ran around (playing tag?) a while before going to the Houston Astros vs. Milwaukee Brewers baseball game. The limited footage of the game in the movie (which included Astros #16's home run) was adequate to identify it as the 4/17/06 game that started at 7:07 PM... on a Monday (not over the weekend). (00:39:45)
Other mistake: Salma Hayek is shot and the bullet goes through her side, leaving an entry wound and an exit would on her body, but not on the nightie she's wearing, at least when she passes by the entrance mirror. (00:05:50)
Other mistake: The lost cape from the mini soldier was blowing out of a return air duct that was actually sucking air in to an air filter.
Other mistake: While exploring the attic, Lane sees a yellow chair in the attic. Trouble is the attic opening is much too small for that size of chair to have gotten through.
Other mistake: Elizabeth Banks' husband says it's 4 in the morning but there's daylight coming through the window.
Other mistake: When Lance and the coloured soldier disembark the tank near the start it's heavily raining, and they get soaked. However, the rest of the crew around and on top of the tank stay completely dry. (00:06:10)
Other mistake: At the end when the ship crashes that part of the city is leveled - we see injured people, but no one is covered in dust or dirt thrown up by the impact - everyone is clean.
Other mistake: The clock on the kitchen wall was at 5:03 PM when Donna asked, "Where the heck can they be?" After an outside scene and returning to the kitchen, the clock was still at 5:03 when Donna said she couldn't find her camera. The battery in the clock could have been dead, but the display time was what could be expected around dinnertime (suggesting the clock was supposed to be in working condition). The "non-advancing" clocks seem to be a common occurrence in movies. (00:10:20 - 00:11:18)
Other mistake: The grave that Clinton dug for "Mouser" was not even close to the recommended minimum depth of 3'. After placing the box in the hole, the cat's remains would have been within about a foot of ground level, which was close enough for the cat's scent to attract animals which might/will dig up the grave. The roots of Mouser's favorite tree should have interfered with the ability of Clinton to dig there without obstructions. Also, some states or local ordinances prohibit backyard burials of pets. (00:24:28)
Other mistake: During the dinner scene we see Finn pour Newgate a drink. Newgate then goes to drink from it when Eliza kicks him so he spills it. However due to the width of the table this should be impossible.
Other mistake: He is referred to as Sir Ryan at the hotel. He isn't knighted until later, after they marry.
Other mistake: During the driving scene in the woods with the Bronco, at least two shots are reused twice.
Other mistake: In the first scenes of the film, we see the truck in which Jenco and Schmidt are going and moving away from Ghost, but while the truck is running we see Ghost inside it, sitting in front of the driver.
Other mistake: In the flashback to Richard's childhood, when he looks from the door at his dad randomly shagging a party guest, the door appears open wider in the POV than it is in the other shots, where the opening barely fits his head. Besides, with the head in that position, he wouldn't see the door handle as shown. (00:02:00)
Other mistake: After the longest introduction ever, a text crawl (in English in the original version too) details the event leading to the titular fight club. It says that the city fell "A PART" and the institution "IS COLLAPSED." Also, it warns us; "cannibalistic zombies are malformed." (00:59:30)
Other mistake: When The Phantom's shot in the leg he somehow gets blood on his sack mask.
