In the big meeting with D'Enzo, he states (referring to Johnny Whitefeather) "And your great-grandfather was one-half Navaho. So what would that make you? One-thirty-second?" This is factually wrong. If his great-grandfather was half Navaho, then he would be 1/16th Navaho (his grandfather would be 1/4 and his father would be 1/8th). Martin Sheen either read the line wrong and it should have been "great great-grandfather", or it was simply written wrong.
When Evan is driving to Olivia's recital, the door lock can be seen moving into the lock position. The auto lock feature engages at 9 mph. Evan had been driving for some time, therefore, the lock should have already been in the down position.
When Evan is in his house the first night that he has Olivia, she comes out of her bedroom and goes to sleep on the lounge chair in the same room Evan is working. When Olivia first gets on the lounge her slippers are near the foot of the lounge. A couple of clips later you will see them near the head of the bed.
