Keeping it down to the 10 guests I'd have to dinner (from any time), right now off the top of my head I'd probaly invite: Napoleon Bonaparte, Winston Churchill, Stanley Kubrick, Marlon Brando, Orson Welles, Norman Mailer, Marcel Proust, Sigmund Freud, Albert Einstein, and Ludwig Van Beethoven. These guys aren't all necessarily my heros (though some are), but at least this way there'd be some interesting table discussion.
