Another wonderful character study occurred in the recent film "Mystic River". Sean Penn, as the father of a murdered daughter goes from being a helpless, completely destroyed man to a murderous vengenance-seeking madman who'd stop at nothing to get revenge on whomever had killed his daughter. You can also make a similar case, in many ways, to various shows on TV, such as "The Shield", "The Sopronos", and the like.

To watch a man walk two very delicate and very different lines of a person, first one so completely out of control emotionally, one that can't put to words the pain and anguish he feels; and then by films end, to have become one who cannot control his wrath and ends up going out of control physically proves that we are all capable of being heroes otr villains. How we cope with a particular situation or how we keep our emotions within us is ultimately what rules the day.

A few other films to watch that depict both sides, honor and dishonor, I suppose would be: "The Godfather", "Se7en", "The Bridge On The River Kwai", "Training Day", "Blade Runner" and "Traffic".

What each of these films have in common is that characters are essentially given the choice between moral and immoral decisions. Even villains can have hearts, and even some heroes can prove to be heartless. It's quite a view into the human soul.

Best of luck on the project!

Take care all.
