Factual error: The pizza parlor's big break comes when the Fireside Gourmet features them on his TV show. Leaving aside the unbelievability of a gourmet restaurant critic visiting a pizza parlor, he appears as himself on his TV shows. Food critics always dine anonymously so that the restaurant can't give them any special treatment. (Movies love to mess this up.) In addition, when they watch his review, he's barely spat out the name of the restaurant when the phone already starts ringing. Barely enough time to dial the phone, let alone look the restaurant up in Information as most would have needed to do for this little-known place.
Factual error: When Tim first takes Kat up to the roof of the house he's working on, it's not clear when in the year it's supposed to be happening, but it's well before Halloween, which marks the fateful end of their relationship, so likely no later than early October. And yet the deciduous trees are all entirely bare.
