US UAVs twice attack the aliens with Sidewinder missiles. Sidewinder missiles aren't a normal payload on UAVs, aren't meant to attack ground targets, and, being IR guided, wouldn't be able to lock on ground targets in either event. What is more, their warheads are comparatively tiny, further limiting their usefulness in this task. The most correct missiles to use would be Hellfire missiles.

As Klaatu is walking down the train platform at Newark Penn Station, in the background you can see signs that say "VIA". VIA is the national railway of Canada and does not have a presence in New Jersey. This scene was filmed in Canada, as evidenced by the signs on the platform and the 1950s style streamlined passenger cars on the track. Neither Amtrak nor NJ Transit uses those type of cars in their trains.

At her mother's house, when Kate finishes with the pregnancy test, its position moves on the counter beside her.

At Pastor Phil's church, when Kate and Brad are preparing for the play and the baby is handed to Kate, the pamphlet jumps in and out of the baby 's grasp between shots - when his hand is not at his mouth.

In the scene where Bella is in the hospital, when the camera is up close to her face, the breathing tubes are right by her eyes, but when the shot is far from her face, the tubes are sitting on her cheeks.

When Bella pulls up in her truck for her first day at Forks High, as the camera pans from her truck as she parks it into shot, you can see the camera and boom reflected in the triangular window.

In the final scene, Penny is wearing a yellow shirt. But, right before the credits, in the picture Penny took of Bolt, Mittens, Rhino, and herself, she is wearing a red shirt.

Near the beginning of the film, Calico is sitting with a cat on his right shoulder. Their reflection is shown in the glasses of a man directly opposite. The reflection shows Calico and the cat in the same position instead of being reversed, as a reflection would be.

Early in the film Hugh Jackman is using a 1990s plastic toothbrush.

When Nullah and his mother are being pulled out of the tank, the stitching on the dummy used for the mother is visible.

At the end of "Casino Royale," Bond is wearing a three-piece suit. Although "Quantum of Solace" begins just minutes later, Bond is wearing a completely different, two-piece, suit.

In the scene where Bond is in the old airplane, it cuts to a scene behind Bond, and in the middle of the screen you can see the camera used to film him in another scene.

At the end of the movie, it's revealed how Alex can tell Marty apart from all of the other Zebras - when Marty walks away from the "camera" it shows the huge bite mark on his backside that Alex gave him in the first movie. However, the bite mark is never seen in any other shots of Marty's backside throughout the film.

The box Alex is in isn't 100% waterproof. Surely some water would seep in.

At the end of the scene where Frank chases the car on a bike, he jumps into the car through the driver's window. You can see broken glass flying, but in the next shot (and the rest of the movie) the driver's window is intact.

When Valentine sits in the car while Frank beats the bad guys up, you can see that she could easily take the bracelet off her hand if she wanted to.
