Continuity mistake: Early in the movie after Haley Joel Osment befriends a bum they are sitting at the kitchen table and the bum pours Haley a bowl of Captain Crunch and fills it over the rim of the bowl. In the next wide shot the bowl of cereal is below the bowl's rim level as they pour milk into it.
Eugene: OK. You know, I'm going to have to consult my spirit guides here, because you tell me that Trevor is withholding from you, but you won't tell me anything specific and you still want me to sit here and divine why.
Arley: Divine why? You always talk like that?
Arley: You go to some big, fancy school?
Arley: Think you can stop rubbing my nose in it?
