Answer 1

if you go to www.imdb.com there is a section called trivia, you will find lots of anecdotes, actors who were considered for the roles, how first draughts of scripts differ from the finished films, input from producers, input from actors, etc etc if you like films its interesting in itself. but im sure this will give you a lot of ideas.
