Who are you? I know I'm supposed to know who you are, being that you're some kind of celebrity. But I do not know where, how, and why you are famous. So, what book did you write? What movie did you starred in? What movie was based on one of your books? Given the case that you've written a book, is there a chance I will need to read it at some point during my literature classes in university? Or are you a physicist?
