We watched Road Games a few nights ago, thinking it might be the film where a menacing truck keeps following a car, but it wasn't! Does that scenario ring any bells with anyone?
Definetly Duel .... (Speilbergs 1st film) ... little fact as well ... in JAWS 1 .. when the shark gets blown up at the end, when its body bits are sinking to the bottom of the ocean, the sound effect used is the noise of the truck from duel when it went over the cliff!!!
