Okay, if Valve was to ever try to make a serious Left 4 Dead film, then they should STAY AWAY FROM THE CAUSE OF THE INFECTION! That plot has been done again and again, and a plot centered on just the story of four survivors from their perspective would be original and thought provoking. If there isn't any traceable cause of the infection, it makes it much more frightening knowing that some crazy scientist didn't just wake up one day and invent this killer disease. Withholding knowledge can be a powerful thing if done correctly. You could delve into events about the first days of the infection, but stick to telling the story of the four survivors in a dramatic and compelling way.
