Although the film belongs to Baker and mcgoohan there are plenty of other famous faces to spot. yes, sid james only ever played one character in all his films- that of sid james- but its an interesting romp nonetheless. I have it on good authority it was filmed around Stanwell moor, west London, and the trucks are "kew" dodges. something no-one has picked up on is that the sequences showing the trucks traveling at speed are obviously speeded up, these old motors were incapable of exceeding 45 mph, even more so carrying 10 tons o gravel (they were only 7 ton design weight) The plot is believable though, the practice of paying drivers "per trip" was and still is a common practice, especially in the tipper sector (obviously to encourage more runs) I know, I worked for a firm remarkably similar to Hawletts. someone has commented on the "coincidence" that all the drivers sleep at the same lodgings- this too was common in the 50's, before the advent of sleeper cabs, drivers would simply find "digs" for the night. also fewer people had their own car in those days, so wouldn't it make sense to sleep close to the job? Made on a small budget in an era where you would need to watch your Ps and Qs and also tone down any scenes of violence, its a classic in my opinion. In those days you'd actually probably be very grateful to be behind one of these wagons, the speed limit for trucks was only 20mph back then!
