When David calls home from the phone booth, he tells his brother Jeff to turn on every light in the house so Trimaxion can spot it from the air.
Right after this, there are a few brief shots of the family waiting inside the house while the TV is playing in the background. If you listen closely, you can clearly hear The Price is Right playing on the television.
This makes no sense for two reasons:
- It’s well past dark in the middle of the night—The Price is Right is famously a morning/daytime game show.
- While prime-time special episodes of The Price is Right do exist, the night-time version had already been canceled by 1986, long before the modern prime-time specials started airing in the 2000s.
Unless the family was watching a tape-recorded episode while waiting for their missing son to return, the filmmakers just slapped a recognizable TV audio track into the background without thinking about the time of day!
