This film catapulted Jan-Michael Vincent to stardom level for awhile, and contained a lot of good, exciting action scenes as well as politically correct assessment of some of the problems of independent truckers at the time. Of course, it contained some action and fighting scenes that are somewhat unbelievable, but in the context of the story, they work. Kay Lenz is the believable, not too lovely hero’s wife who downplayed her attractiveness displayed in later films. There are lots of eye-pleasing shots of trucks and highway mayhem, and, of course, from a trucker and real-life perspective, lots of technically inaccurate scenes, but, all in all one of the very best trucking movies ever made — and I’ve seen ’em all! Good cast, good flick. This $2 million film went on to be a big grosser.
