Craig Miller was the Director of Fan Relations for Lucasfilm from 1977-1980. As you might be able to guess, there was a lot going on in the early Star Wars fandom during that time, from churning rumors in Starlog to creating the Fan Club and Bantha Tracks to crashing Illinois 800 numbers.
Mr. Miller has some great stories about what it was like to market this brand new sci fi movie called … Star Wars.
