Legion

When Audrey is in the minivan, one of the possessed scratch the window leaving visible marks, in the next shot the scratches are gone.

When the old grandma toward the beginning of the movie bites Howard's neck, Kyle rushes over to help and starts to take off his scarf to apply pressure to the neck.

When the next scene pops up, the scarf has turned into a napkin.

The next scene shows it again as a scarf.

The location of the Chevrolet Astro van's parked position at the gas pump changes during shots after the father exists the vehicle.

After Percy gets bathed in acid, there is a shot where you can clearly see that his back is intact, but after that he falls revealing his back completely acid burnt.

At the end while driving away in the van/station wagon, the gear shift is clearly in park.

You see it again as it scans back to show the guns in the back.

When Kyle first arrives he asks Charlie for a cigarette.

Her cigarette keeps changing lengths during this scene.

Obviously a different cigarette.

When Jeep, Charlie, Audrey and the newborn are instructed by Michael to leave the diner, they get into the vehicle and are seen moving slowly through the crowd of people, who part to let them pass.

The problem here, however, is that, though the vehicle is moving forward, the camera shot (through the driver-side window focusing on the rear-view mirror), shows the people in the mirror as going from left to right with the cars movement, which indicates that the vehicle was movie backwards when the shot was filmed.

When you first see the truck carrying the pipes which the view is from the back of the truck looking forward you can see two stacks of pipes on the back of the truck.

But when you see a shot of the truck later there is only one stack of pipes.

When the power goes off in the diner, the jukebox isn't playing, but when the power comes back on it is playing.

When Michael shoots Burton, the cop seen early in the film, a crash mat can be seen on the driver's side of the patrol car as Burton falls to the ground.
