When Rod is filling up the van and the birds start attacking, he lays the gas pump nozzle on the ground. In the next shot as the van is leaving, it is hung up on the pump.

The man who robs Rod of gasoline is walking backwards when he is attacked by a bird which slashes his neck. As he is still walking and before he falls down, his face is OK. In the next shot he has a wound on his face as well as his neck.

When the Cowboy pulls a gun on Rod and demands that Rod sell him some gas, he draws the gun and holds it straight out with both hands. In the next shot when the Cowboy voices the demand, he's holding the gun straight out using only his right hand.

During the news cast, the television screen showing the stock car race footage has "Getty Images" super-imposed over it.

In a number of shots, the badly inserted CGI birds disappear before the shot ends, and in at least one occasion, they drastically change position just before the shot cuts.

When the forest is set on fire, one shot fades into the next, and during the crossfade effect, the fire disappears.

It is very obvious during the bird attack scenes that the characters are either shooting their guns or swinging their hangers at nothing so that the birds can be CGI inserted later.

Some of the birds fly without moving their wings, even when other birds in the same shot need to flap their wings to stay in the air.

Near the end of the movie when Rod is shooting at the birds with the pistol from the van, the recoil is out of sync with the sound of the shots.

While Rod and Nathalie wander toward a flock of birds, the cameraman's footsteps can be heard crunching in the sand.

During the closet hanger attack sequence, one of the guys struggles to unlock the van door and the camera (including its tripod) is reflected in it.

Camera shadows in some scenes.

The clerk at the convenience store tells Rod that he can't use the telephone because the lines are down, yet he runs Rod's credit card through a credit card machine, which uses telephone lines to process transactions.

When the characters went on a double date, the films advertised on the marquee outside the theatre were released at the end of November 2008 but yet Rick and Nathalie later attended a Half Moon Bay Pumpkin Festival which was more than a month earlier in October.

During the early attacks on the van, the other traffic proceeds normally, as if nothing strange is going on.

Rod whines about how much he paid for the gas when the other guy tries to steal it, yet after the guy is killed he walks right past the gas can and leaves it (and the gun) on the ground and then takes off in the van.
