When Jake and John drive through the parking lot and stop to talk, John parks in front of two large trees, one directly in front of the car. The inside shot from the back seat has no tree visible through the windshield.
This film takes place in Los Angeles in 1989 but nothing about the Tremonts' house or neighborhood look like California or any neighborhood in Los Angeles. Short of a brief beach scene that shows a couple palm trees, the entire film looks like the Northeast because it was filmed in and around Boston.
