What do you think?

I think there could be an amazing movie or book about an immortal man, there would be so many interesting questions.

What would a man like that be? How would he be affected by the millenia? What would his perspective be? What would his life be like/have been like? What would he think? What would he feel? How would he speak? What would he look like? And I'm sure more questions could be raised.

And some of these questions could be answered or addressed in the literature or movie.
