After Jane leaves the hospital, in various shots his shirt sleeves are rolled up and his cuffs aren't visible; then a moment later in a different shot, his cuffs are visible.
When the camera is shown too down at the falling tea cup in slow motion. You can see 3 feet. One set being the actor and the 3rd presumably a crew member dropping the teacup in a way to make it look good to the camera. Later on the same scene is shown but cropped a bit more to cut out the foot.
