Continuity mistake: As Henry's secretary pours cream into his coffee, in one shot the level of coffee is right at the top of the cup. But in the next shot, the level of coffee has dropped, as the secretary continues to pour cream.
Continuity mistake: In the scene where Henry is first learning to walk with the walker, he is in front of the table where he had been sitting. They show a shot of his feet, and there is only tile floor stretching behind him. He only took a few steps and the table (with the attached drawers beneath) should still be visible.
