When leaving Hank's room, Sandy alternates between having a bag on her shoulder and not having a bag on her shoulder in different shots.
After picking up Becca from the party, Hank and Karen have a glass of wine together. The camera shows Karen pouring herself a glass of wine and then Hank's. The camera switches to Hank and then back to Karen, where she is shown pouring her glass of wine again.
In the opening helicopter shot of the coast line, the cars are all in reverse.
