Duel.
Here’s Duel, from 1971. Famous as Steven Spielberg’s feature-length directorial debut, Duel is about a guy menaced by a mysterious truck that he can’t shake.
The movie does a lot with a little and there aren’t any wasted moments. I’ve seen mixed reactions to Duel over the years, but it hit me pretty hard and I thought it was way effective. Scary, too.
(But I still think it should’ve been called Fuel.)
