Corrected entry: In the final scene with the grandpa and the boy the grandpa's hair gray (as it was in the rest of the movie) but during a close up when he at the door about to leave his hair is dark brown. It changes back to gray right before he leaves.

Correction: It only appears dark brown due to poor lighting during that shot. If you look closely, you will see that his hair never actually changes color.
