Adam (as David) says in his childhood home there are 10 windows; 11 if you count the star in the front door. When Dr. Harding drives to his childhood home, which the audience knows is the one he was talking about because of the star in the front door, 12 windows are visible, and that is not counting however many there are on the unseen side of the house.
Before Dr. Cara Harding's first interview with "David Bernburg," as she is preparing she's writing with her right hand. But when the interview starts and for the remainder of the movie, she writes with her left hand. Also, the first picture she hands him changes directions between shots.
