Other mistake: Royal and Etheline are walking in the park and it is written in the book. But it's also written "Childrens play in the trees". They are alone in the park. There is only Henry Sherman at the end and a dog on the other side of the pond.
Other mistake: After everyone finds out Royal does not have cancer, Chas storms over to the yellow phone. You can see Chas is making movements as though he is pushing buttons on the phone to make a call, and there are accompanying button pushing noises. However, when he's finished, you can see it is a rotary dial phone.
