Continuity mistake: When John Bell has blood coming out of his mouth, his left hand is covered with blood. When the camera shot switches it is his right hand that is covered in blood. Then when the shot switches back to the first angle the left hand is back to being the hand that is covered in blood.
Continuity mistake: Lucy starts running up the stairs and down the hall with a burning candle in a candleholder in her hand. As she starts down the hall, you see that the candle flame is light yellow (typical color for a candle) and is flickering. About halfway down the hall, the candle flame turns blue and burns steady (like a gas flame), then turns back to a light yellow candle flame as she approaches her daughter's room.
