In the traffic jam scene, Tom pulls away at a green light. Cut to a Plymouth station wagon driving through a red light on the cross street, about 30 feet away. In the next cut a Ford Galaxy wagon is pulled up right against the driver side of the Wedloes' jeep. In the next cut there is no car pulled up against the jeep and the Plymouth wagon swerves to avoid hitting the jeep. The jeep stalls, and the Ford wagon pulls up right against the jeep in the next scene.
When Ben jumps from the railway bridge into the river he is obviously a man in a bear suit.
