I understand your point about 'real world' context but it is entirely beyond the capacity of an editor here to determine, beyond available facts, that one person had more of a hands-on role than another.  In the context of The Spirit article, the original text accurately reflected that Oddlot (Del Prete and Pritzger) entered into a collaboration agreement with Batfilm which included Melniker and Maier as well.  That's a 'real world' context.  Typically, in film and tv production, different elements bring different strengths.  It seems to me that if article after article reflect the participation of certain folks, the evidence grows that the industry agrees who is important to the film ...and who isn't.
