Continuity mistake: Right before Collette Bradley leaves Kimberly in the car, her car key is still in the ignition (the keyring is visible). But in the immediate shot of her getting out of the car, it is out of the ignition and on the seat next to her.
Visible crew/equipment: When Cal and Ben go to the doctor's office, a cameraman operating a camera is reflected in the glass door as Cal and the doctor enter.
