Items on the bar move around between shots. There is a wine glass on the bar next to Ben that isn't there when he sits down or stands up. And there's a large napkin/straw/coaster holder that is at the far end of the bar when Ben comes in, moves right next to him when he sits down, and disappears when he stands up, all without the chance for the bartender to move it.
The food throwing scene at the cafe is inconsistent between shots. First Lulu shoves a full plate of food and a mustard bottle behind the bar. In the next shot the mustard bottle and plate are back but the food is already all over the bar and the plate is empty, and the old man's glasses case is replaced by just the glasses. This time she just shoves the cups and mustard bottle behind the bar as well as a blue hat that was not there before, and also knocks over a bowl of artificial sweetener. In the next shot the bowl of sweeter is upright, a newspaper that was near Lulu is now near the old man, and the plate and glasses are gone.
When Lulu is lying in bed being questioned about her medication, she lights a cigarette. She takes it from her mouth in her left hand but in the next shot it is in her right hand as she ruffles her hair. The cigarette is in her hand with her arms crossed over her head but in the cut back to the shot of Ben as he talks she has taken a puff even though no time has passed for her to do so.
While in a park near midday, Ben has two distinct shadows. This occurs when Ben is walking down the path to get his cell phone back from Lulu. The shadow from the sun is seen to his left and the other shadow is on his right, seen against some greenery and a tree. Possibly from extra lighting behind the camera.
