Character backstories in Sorcerer vs. Wages of Fear
There are a lot of obvious differences between Wages of Fear and Friedkin's reimagining of the same story/premise in Sorcerer. To me, the biggest difference isn't in the particular details of the characters, but in the fact that Sorcerer gives us backstories of every key player, whereas Wages of Fear leaves the question of who they were before getting stuck in a remote South American village (and how they wound up there to begin with) much more murky.
Do you prefer knowing how the main characters wound up castaways in the middle of nowhere, or do you like the idea of leaving it up to the viewer's imagination?
