When Courtney leaves the wedding to look for Christina, the wedding march has begun as she leaves the pew and starts up the aisle. The next shot is of her outside the church and on the lawn, but the music has played continuously without enough time for her to have walked that far.
When Vera is displaying mannequins in front of her store a car drives by hitting and dismembering the one in the blue/green dress, but when Roger and Peter are bringing the mannequins they only bring in the red one which only lost one leg.
When Christina and Courtney are in the Car on their way to the wedding, they look at their map and mention taking Interstate 95 and 40. Those interstates are located in the east coast. Interstates near San Francisco are 101, 880, 80 and 280.
When Peter turns the pages in Vera's mailing list guest book and lands on "Christina Walters loves Peter," the area code written is "94587" which is the area code of Union City, California, a smaller city in the east bay area.
