'The Wages of Fear'/ 'Le Corbeau' & 'Lord of War'
The primary difference would be that the human element would have been larger and the scope smaller.
But let me backtrack for a minute.
Clouzot, who worked at the same time as Alfred Hitchcock, specialized in that same sort of film. The difference is that Hitchcock is a household name in America, and Clouzot is probably known to filmmakers and those who have heard of the remake of his film 'Diabolique' with Sharon Stone.
In France, during the time of the Nazi occupation, he made a fascinating film about the nature of accusations or snitching on your enemies. At the time, the film fell under extreme scruntiny from both the Nazi sympathizers as well as the loyal French Resistance. This placed him in the awkward position of being played against the middle.
All this notoriety obscured the film. The film works as a scathing attack on the nature of conformity of the very people who despised it. Thus, all the people who critiqued the film were, in a way, guilty of the crimes the film was leveling at the public. How else could it be explained.
The plot of the film is fairly simple. A doctor comes to town from Paris. He keeps to himself, outside of an affair with a local woman and his work. His doctoring leads him into quite a dilemma. After saving too many women from problematic births (the babies die), he is labeled an abortionist by a letter writer who names themself The Raven.
The letter writer writes to everyone in town and, after a short time, The Raven starts writing to everyone in town about gossip involving there neighbors, lovers, and rivals.
Everyone in town starts suspecting each other, and it's not long before some innocent is fingered as the culprit.
In another of Clouzot' films, 'The Wages of Fear', a band of rough necks, from all-over-the-world are contracted to move nitroglycerine to an oil field. An international group of four is selected by an American company to drive the nitro to the oil field. The trick is that the path to the oil field is a bumpy one and there is a good chance that one if not both trucks will explode.
In this film, over an hour and half is dedicated to the trip. The slow and meticulous trip includes a stop to blow up a rock, a tight turning point that includes a perilously positioned half bridge, and an oil slick that stops one truck dead in its tracks.
In Niccol's 'Lord of War', he uses international gun running to pint a portrait of a man, who truly believes that he's good at one thing. To linger to long on the fact that this man is a bad man would defeat the purpose. Of course he's bad, he's sells guns to war lords (a nice inverse of this phrase and 'blood bath' are included in the film).
It's sort of like getting lost in the fact that 'Le Corbeau' created a fury in France. It did so because while the director has a point of view about the character and the film, it isn't the most important part of the film. The most important part of the film is how the character acts in the situation he finds himself.
Niccol's hero views his work as a business. A business that he tries not to take home.
In 'Le Corbeau', Clouzot's hero tries to do the same. He attempts to brush off the fears of the public.
There is a difference between the characters that is important, but you have to watch the films to see what that is.
Both characters find varying degrees of success in their pursuits. Both find that outside obstacles will influence those you live with. That without place there is no home.
The films can be viewed as attacks on the systems of government or the nature of people (which are virtually the same thing). But mostly they are discussions of character, who has it, what it takes to have it, and how you live with it.
