George Lucas isn't known for doing many interviews and especially ones that he is asked the right questions, by the right guy (Charlie Rose) and him being mostly modest throughout the entirety of it. Speaking about a range of topics from his filmmaking start, his future goals and of course Star Wars. The interview is a hour long, so whoever is interested in his story and his thoughts on Star Wars of past and present. Should see it from beginning to end.
