Movie idea: Murderer sentenced to 1,000 years, miraculously lives that long and has to adjust to life on the outside. Will he kill again?
This was kind of done. Mr. Nobody is the last person who isn't going to live forever, and they prod at his memories, and it ends up showing several paths his life could have followed. Also I think Bicentennial Man had this aspect as well. - OCoG of FF, Jimminy
