Sequel idea?
It can be titled Duel 50 years later.
Plot includes the old broken down truck sitting in a junkyard when all of a sudden, the devil swoops in and possesses the truck via evil spirits. The truck has no actual driver. The truck leaves the junk yard and goes after the children of David Mann. David Mann himself is still alive but is in his mid 90s. Obviously a different actor would have to be cast. When his children complain they are being followed and terrorized by the truck for unknown reasons, David Mann cannot believe when he showed a pic of the truck from his sons cell phone. This has potential to be the best sci fi horror movie of all time
