When Larry is demonstrating his "Sonic Palette", he creates a rudimentary painting, though still largely devoid of paint. Just seconds later, as he and Louisa kiss and the machine resumes painting from the captured noises, the painting is almost full, as if it had been active for very much longer (as estimated from the earlier brush stroke activity).
Edgar is heavily covered in mud as a result of Lennie's car, but a moment later, he is lightly covered.
The position of Louisa's hands and her facial reactions change as Larry's artist friend shoots at the balloons tied to her canvas.
Near the end, Louisa and Stephanson are on a couch which rises high into the air. In a medium shot, a white lampshade in the background that is below his shoulder. In a following medium shot, the bottom of the shade is about 8 inches above his shoulder. In the next long shot, the top of the shade is at least a foot below the bottom of the couch, a difference of about 4 feet between shots.
When Louisa first meets Larry in the cab, he's eating a banana with a bruise on the fruit and the peel. In the next scene, it's a different banana with no bruising.
Anderson flies a Boeing 707, which no pilot would attempt to operate by himself. A co-pilot and an engineer are also needed. Also, he is not wearing a headset.
When Crawley punctures the pipeline with his tractor, the pipeline workers appear almost instantly. Unless they happened to be in the area checking the pipeline, the first indication of the puncture would be a detected pressure drop at a control station, followed by the dispatch of personnel. They might have several miles (or more) to check before they found the leak. There would probably be several hours before it was discovered.
At 27:40, the sign on the store misspells "draperies" as "draperys."
Louisa is clearly hit by one of the robotic paintbrushes in the painting sequence with Larry; when she's walking after him among the animated brushes, the contraption hits her on the head.
At Pinky and Louisa's pool, several bright stage lights are reflected in Louisa's sunglass lenses while she's seated and in Pinky's after he comes down the stairs).
The flight deck of Anderson's plane is not a Boeing 707, as the exterior shots establish: There is no flight engineer position, and the control yokes appear to be from a Douglas. In addition, there are a number of instruments behind the pilot's position.
