From Batman #437:
...What prompted this letter, however, was a number of articles in the Comic Buyer's Guide on the forthcoming Batman movie. My congratulations to you and to Warner Brothers! Superb! Batman looks eminently formidable and Bruce Wayne has never looked so debonair. Jack Nicholson's Joker is chilling and the Batmobile is awesome. This is going to be a blockbuster! I've seen the previews, and the characters appear true to their comics form. It seems you have better luck transferring your characters to the movies than your major competitor. What's the trick?
Thanks for great comics and movies.
No trick, just ingredients. You start with a solid, definable character and he sort of takes over, no matter what the medium.
Yep. DC > Marvel. Warner Bros > 20th Century Fox.
