Re: Who were the main characters?
Uh, Wikipedia? Really?
The term "extra" isn't even an official term used in the industry. I assure you that people like "You mess with Spidey, you mess with New York!" guy are seen as and referred to as extras within the business.
Can you cite any sources to back up what you're saying? If Wikipedia's so bad, what sources do you have that are better?
