- Creator-Preferred Adaptation: Surprisingly, Richard Matheson, known for disowning most of adaptations of his works as being too far from the original, genuinely liked this one - this despite the screenwriters changing location and ending of the story.
- Retroactive Recognition: The actress who plays the ghost, Jennifer Morrison, went on to starring roles in House, M.D. and Once Upon a Time.
- Throw It In!: In the scene where Tom gets angry after digging in the back yard and kicks the bucket towards the wall, it was not suppose to hit and break the window. This was a "happy accident" and it could be used in the film as Kevin Bacon stayed in character and continued the scene.
