Continuity: When Rob is talking to Kate outside of the courthouse, the collar of his jacket changes positions between shots.
Crew or equipment visible: When Carl and Angie argue, a crew member's light is reflected in the rear of Carl's red car.
Errors in geography: When Angie goes into labor, Kate drives her to the hospital. In a long shot, they drive over the Benjamin Franklin Bridge to Camden, NJ. Later, they arrive at the University of Pennsylvania Hospital.
Factual errors: Angie cannot open the door to Kate's "space car," an Audi A6, because it is locked, despite pulling the door handle several times. If an Audi door is locked, the first pull on the handle from inside unlocks the door, and the second pull opens it.
Factual errors: When Angie and Kate are driving through Kate's neighborhood, all of the parked cars have front and back license plates. Pennsylvania only requires back license plates.
Errors made by characters (possibly deliberate errors by the filmmakers): When Kate firsts meets Rob at his juice bar, she never pays for her purchase.
Continuity: When they are test tasting the soups, Barry picks up "c", which is the green pea soup. In the next take, the carrot soup is labeled "c", and "b" is now empty.
Continuity: Before Angie arrives at Kate's place to move in, Kate is sitting in bed with the pillows and sheets displaced. At the end of the scene, we see Angie passed out on Kate's completely made bed.
Miscellaneous: For the courthouse scene Angie is wearing a white shirt, red tie and vest. This is the same costume Olive wears for the talent portion of the beauty contest in the movie Little Miss Sunshine (2006), perhaps in an homage to Actor Greg Kinnear, who starred in both movies.
