Before Sunset

When Jesse and Celine sit on a bench in the park Jesse has his arm around Celine in one shot, in the next the his arm is gone.

When Céline and Jesse are at the Café, a wire (of a microphone) is visible in Jesse's shirt.

When Jesse and Celine walk from the book signing to the cafe, the couple they pass window shopping is wearing different clothes depending on the camera angle.

When Celine and Jesse are entering Celine's apartment, she opens a "right hand" door, the next shot (from the inside) shows her opening a "left hand" door.

It is not the same door.

The boat on the Seine, moves to the east, but in one shot, the boat moves to the opposite direction (The Eiffel Tower is clearly visible, which means the boat travels to the west).

The differences between shadows and no shadows on the wharfs of the Seine are also indicating this.

A change in street scenewhen Celine tells Phillippe that they have arrived at her apartment, the view through the back window is of one way traffic, but when the car does pull over and they get out, the traffic is two-way.

After getting off the boat, Celine hugs Jesse.

The position of her arms changes, first right above left and then left above right.

While walking in a park, an extra passes Jesse and Celine.

When the camera angle moves to their front, he passes about 10 seconds later.
