At 57.30, you see Jenny coming out of the house with a box and three boxes on the ground next to her car. She puts the box in her hand in the car, she then takes up one of the boxes on the ground, which leaves two boxes. She proceeds to talk to her friend. When the shot opens up the boxes are no longer on the ground and drives away.
Owls fly silent so their prey cannot hear them. Their feathers are softer and therefore quieter against the wind.
When Robert stops by to sneak up on Jenny's house the 2nd time, there is no snow where he parked his car on the main road. But there was a few inches of snow in Jenny's yard and the woods around it.
The speed limit sign in Robert's neighborhood says 40, which is KM/hour as they post speed limits in Canada, not miles per hour as in the USA.
After Robert's landlord inquires about Robert moving out, a city shot is shown. The city shot is filmed in Seattle, near the I-90/I-5 interchange...with the Smith Tower off to the left.
