The house used for exterior shots of Gull Cottage had a much more elaborate front yard that included at least eight steps up to the front door versus the interior studio set that only had two steps up.
When the station wagon is driving away from Gull Cottage, the ocean is on the passenger's side. The car then turns around to head back, putting the ocean on the driver's side. However, when it pulls up in front of the cottage, the ocean is again on the passenger's side.
