Frank Miller and Will Eisner had a long history together. Their friendship and artistic viewpoints (which were not always the same) were brilliantly laid out in the book Eisner Miller by Charles Brownstein. At this year's Comic-Con, Frank Miller discussed his upcoming adaptation of Eisner's classic comic The Spirit . He recalled his first meeting with Eisner and the 25-year long debate their first encounter led to. He also unveiled some amazing footage of The Spirit , which opens this Christmas.
