El transportista

It's no wonder Guy Ritchie was attracted to this story, and liked it enough to remake the film, Hollywood style. Le Convoyeur is the better film, although Wrath of God is admirable as a thriller in its own right. Le Convoyeur has better character development, and doesn't have distractive subplots involving the robbery gang. I don't want to spoil anything, so give it a watch, and judge for yourself.
