[net.movies] Poltergeist Query -- Slight Spoiler

sjb (07/18/82)

My apologies if this has been brought up before, but I just
saw Poltergeist tonight and have purposely avoided the discussion
on it so that I would be able to see it without knowing what
would happen next.  When Steve was first talking to the
parapsychologist, he said that his wife was 31 years old and
his daughter Dana was 16.  Unless she was adopted, which was
never said, this means that she (Dana) would have had to have
been born when Diane was 15!  Any light on this?
