Revealing mistake: When Charlie and Daisy get the flat and have to hitch-hike, and Daisy takes off her shoes to run to the car that has stopped, the bottoms of her feet are already filthy (presumably from having to do the scene over and over).
Audio problem: In the scene where Charlie is handing the girls their wine, Bill is speaking to his buddy, asking him if he likes his coat. Watch his mouth, the spoken words do not match his lips. (00:15:30)
Continuity mistake: In the first scenes at the pizza parlour, Julia Roberts is taking a pizza to a table and picks up a half full jug (pitcher) of flat looking beer. By the time she gets to the table to deliver the pizza the jug is full and has a frothy head on it.
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.
Continuity mistake: When the girls steal Bill's truck, one toplight is broken. When they arrive at the country club, all are working.
Continuity mistake: In the scene where Daisy is running from Charlie's home after he ruins dinner she is carrying a clutch purse; once she is outside she no longer has the purse.
Visible crew/equipment: When Daisy and Kat are in Kat's bedroom, Daisy is looking in the mirror and you can see one of the production crew members in the mirror.
Other mistake: When JoJo is babysitting Phoebe, Kat and Tim run in from the rain. His arm had been around her briefly but when she is in the doorway, he is behind her and both his hands hold up a raincoat. JoJo had made up an excuse about Kat's mother being ill to cover for Kat and Tim's absence. Kat and JoJo leave and have a discussion in the car about whether Tim's wife knows about them. JoJo says "So he had his arm around you, so what, right?" But JoJo had not seen his arm around Kat.
