The situation with Spawn is especially unique because the man writing, directing and bringing this character back to life on the big screen is the very man who created him in the first place, Todd McFarlane.
Costumes rank up there with casting as things that comic book movie fans sometimes jump to conclusions about, sometimes causing the community freak out prematurely.
So you’ve got to think that whatever he does with Spawn’s costume, it will remain true to the spirit of the character and probably look ridiculously badass.
This all gets back to a desire for faithfulness to the source material, which helped to create the audience in the first place.
