Continuity: Just before the first alien tripod breaks free from the ground and cracks are appearing in the street, the front of the church cracks, and rocks away from its second half. In that shot, in the view from behind Ray, he places his right foot on the curb, while his left foot is on the road. In the next shot facing Ray, both his feet are on the curb.

Continuity: When Rachel runs to her mom, in Boston, in the side shot of Mary Ann she’s already gone down the stairs and crossed the sidewalk towards her daughter, yet in the next shot it’s Rachel who crosses the sidewalk towards her mom, who is still up at the center of the stairs.

Continuity: When Ray throws the bread with peanut butter at the window it lands dead center. However, in the next close-up it’s off to the side of the glass, in order for Ray’s and Rachel’s reflections to be seen clearly. The slice of bread differs as well.

Continuity: When Ray breaks the window with the baseball, the characteristics of the hole differ between exterior and interior shots.

Continuity: When Rachel watches TV, there are things such as books and take-out food on the coffee table, which change position in following shots.

Continuity: When Ray speeds past Manny’s there are long shadows cast, but in the next shot when he pulls into the driveway shadows are gone. When he, Mary Ann and Tim speak the shadows are back only to disappear in the next shot, and so on, all depending on camera angle.

Continuity: As the News Producer speaks with Ray amidst the plane wreckage, her black bag, her actions, and how she hold things such as food trays, change abruptly in consecutive shots, while Max searches for food in the locker.

Continuity: After losing the van the trio sit in the diner, and things on their table repeatedly change, such as when the gunshot rings out. Robbie first flips the coffee cup upside down, but in the next shot when Robbie turns the cup is upright, only to be upside down again when Rachel runs into his arms.

Continuity: When the asphalt quakes in front of the church in the overhead shot, just as the huge gush of water shoots up from the ground, in the foreground a person is leaning way out their window aghast at the goings on. In the next shot that person is gone and the window is shut.

Continuity: Mary Ann pulls the cord out of the iPod and holds it with the screen facing her palm, as she explains about Robbie’s Algeria report. However, in the next shot the iPod is held in her hand the opposite way.

Continuity: After the ferry disaster, the trio swim to shore and climb up the bank. In the side shot Ray holds Rachel’s left arm and Robbie holds her right arm. However, in the next back shot Ray holds Rachel’s right arm, and Robbie holds her left.

Continuity: Whilst Robbie is helping the people onto the ferry in the overhead shot, Ray holds Rachel beside a red car down below as they are both avidly watching Robbie’s heroism. However, in the next close-up Ray is just now approaching the car, amongst a greater crowd of people.

Revealing: When the tripod is tipping the ferry over, people fall over the rail and cars slide toward it. You can see the cars stop short of the rail so they don't smash into stuntmen, even though they are jammed against the rail in the next shot.

Audio problem: After Ray and Robbie's argument, as the soldiers drive by, when Rachel shouts, “Who’s gonna take care of me if you go?” Robbie looks at Rachel and says something to her, but nothing is heard as the shot cuts away to Robbie picking her up.

Continuity: After Ray walks out of Mary Ann’s destroyed house, he sees Max on the airplane wreckage. In the first shot Max’s body faces out, towards Ray, as he drags the food locker, but in the next overhead shot Max’s body faces the seats. His position and things on the plane also differ.

Continuity: When Ray heads upstairs from Mary Ann’s wrecked basement, there is a mess beside the stairs. However, in the next shot looking down, there’s no mess near the stairs, furniture differs, and now there’s a wicker hamper that appears out of nowhere.

Continuity: When Ray and the two guys head to the spot with 26 strikes, there is a crowd of people walking behind them in all the close-ups, yet, in the overhead shot hardly anyone is behind them as they approach the hole, and there was no time for the crowd to move ahead or disperse. Additionally, some of those people who are already positioned at the center of the crowd, around the hole, were just behind Ray in the previous shots.

Continuity: When Ray runs out of the house and meets up with Robbie, the cars and pedestrians very noticeably differ between consecutive shots while they talk. (Not due to cars being pushed.)

Continuity: While the aliens rummage through Ogilvy's cellar, Ray and Ogilvy have a tense, silent tug-of-war with Ogilvy's gun, and their arm and hand positions differ between consecutive shots.

Continuity: When Ray tries to quiet Ogilvy, and then decides to kill him, the pattern and size of the sweat stain on Ray's shirt differs repeatedly in the following shots.
