How do you portray that though? Ultimately the best superheroes are the ones that have a reason to be superheroes.
Him just waking up one day and seeing 'Okay, I'm going to save the world because I have all these powers' is going to be a little difficult to portray on screen if not impossible.
.
But why do people keep suggesting that unless he has some tragic loss, he can't have a 'reason' that pushes him.
As I've said a hundred times, you just have to have Clark encountering the struggles and suffering of the WORLD. It doesn't have to be someone he knows dying because that's just Clark Kent for you - he is driven by his empathy. His ability to really see and care about people because he sees so much more than anyone could know, can hear so much more.
I don't think it'd be difficult to show at all. Showing a guy who has the ability to be anywhere in the world in minutes, travelling, running into all sorts of disasters that he tries to help in secret, getting frustrated at the times when there have been casualties BECAUSE of his secrecy and it's limitations.
And then looking around at those casualties, listening in on corrupt politicians, seeing bribes through closed doors with his x-ray vision, seeing families trying to survive with illness caused by lack of nutrition because they are starving...
Wouldn't you do something about it? If you had the power, wouldn't you become a hero? What is so unrealistic about that?
In fact I'd say it's more realistic from my point of view, to dress in an outlandish costume and announche yourself to the world as a spectacle because your driven by the need to change the world, to be seen by everyone as a symbol for good, hope, peace etc.
How do you decide to become Superman because your father dies. Can someone explain the thought process because I don't really see it.
Superman is not Spiderman driven by the death of his Uncle Ben and his strong words 'with great power comes great responsibility'. He is not Bruce Wayne, driven by his hatred of the crime filled underworld that robbed him of his parents, of a happy childhood.
Superman is just a great man.
The world is not THAT cynical that people will find it difficult to accept that you can become a hero just because your a good person.
