Factual error: When Kate is driving Angie to the hospital to deliver her baby, she is going over the Ben Franklin Bridge towards Camden in New Jersey. However, the next morning, the exterior shot of the hospital at which Angie is staying shows a sign saying "The Hospital of the University of Pennsylvania," which is in Philadelphia, not New Jersey. (01:26:35 - 01:30:20)
Factual error: When Kate gives Angie a ride back to Kate's house/apartment, the outside scene shows a road sign for PA-51. PA Route 51 is a road in southwestern Pennsylvania, not a road near Philadephia, which is where the film is set.
