When Wanda picks up Lester in her car when he is sweeping the sidewalk in front of his store, one of the scarf's ends hanging down alternates from in back of her to in front of her to in back of her again.
When Lester jumps into the sewer opening in the street, the burning lantern is on the side opposite the oncoming car directly in front of the manhole. After the car passes, not having hit it, the burning pot has moved about 60 degrees and is off to the side towards the middle of the street. After Lester has climbed out and retrieved his repairman's kit, the pot is back to its original position.
When Leopold hits Lester's repairman's kit in the street with the car next to the manhole, the case is totally destroyed. However, the case is absolutely empty, yet Lester was supposedly on a service call.
While riding in the back of Lester's repair van after picking up Wanda by the side of the road, Peter Flint falls out of the back of the van immediately after it hits a large pothole in the road. When the shot changed to Pete sitting in the road, there is no large pothole in sight.
