Different strokes Funkster, that's all...Speaking of strokes, I had read the original short story in a Playboy I'd swiped from my older brother's room. The hard part(sorry) for me when watching the movie on TV a year or so later with my dad in the room, was not to prematurely ejac--(sorry again, I'll stop it now)--umm, was to not say something in advance along the lines of "Wait'll ya see the rattlesnake farm"...
But to this day, I find the film, and story, fascinating. Weaver's character has a boring job. he's kind of a milktoast. And there he is one day, doing nothing special in his boring way, and for some bizarre reason that's never explained, this truck comes after him....No real reason given. Nothing ever explained. Just a truck. Must have a driver, I suppose, but we never see him...Or her...Maybe in an alternate film universe, Thelma & Louise didn't blow up the idiot's tanker, and instead, they stole it and started terrorizing ramdom dudes.
Very Hitchockian indeed....I'm not sure what my reaction would be if I watched it again. After reading your thoughts, I probably won't...I loved it then. I might not now. Some things are best left alone.
