Pretty sure he put that huge space gap to keep that information away from people who haven't seen it. Though now after reading that my immediate guess it that DeNiro is the bad guy and ended up killing the mom or whatever in the movie a long time ago and perhaps the ghost-child thingie talking to the girl.
edit: Oh and I love Deniro but he's def taken a turn for the worse as of late.
