The title of the paper that Eddie is typing is "A Sound Like Someone Trying Not to Make a Sound." As he is typing it the first occurrence of 'Sound' is upper case. When he finishes typing the title 'sound' is lower case. Later in the movie when he looks at the paper 'Sound' is upper case again.

The flashback scene in the car with the boys is supposed to take place during a heavy snow fall, and the back window and tail lights of the car are supposed to be covered with snow, but the window is completely clear.
