And...

Okay, dumb question, but why would anyone care if an actor portraying a comic book character has read the comic in question?

I mean, scriptwriters, yeah. You would hope the scriptwriters have read the damn comic. Directors too. But actors? Their job is to act according to the script/direction. I'm not saying it doesn't take skill, but it seems to me that if the part's well defined enough, the actor can manage.

And there's nothing stopping the director/writer from handing the guy/gal a damn trade paperback.

Sometimes we geeks are SO WEIRD.
